Updates to 23andMe Paternal Haplogroup Assignments

With the holiday season upon us, 23andMe is sprucing up its paternal haplogroup tree! With 23andMe population geneticist and Y-chromosome expert David Poznik at the lead, we’ve updated our Haplogroups paternal-haplo-001Report to reflect significant developments in the field over the past few years. We’re also excited to introduce yHaplo, our new open-source software for researchers.

Major Refinements to the Y-Chromosome Tree
Each generation, fathers pass down copies of their Y chromosomes to their sons. Small variations arise over time and accumulate in patterns that uniquely mark individual paternal lineages. To trace the evolutionary history of these lineages, scientists study DNA sequence differences between and among modern populations and have built a “tree” that shows how global Y chromosomes relate to one another.

However, our understanding of the Y-chromosome tree had, for many years, been limited by our incomplete knowledge of Y-chromosome diversity. Because paternal haplogroup names reflected the structure of the tree, each new insight required renaming haplogroups, and this made it difficult to interpret paternal haplogroup assignments from one year to the next.

Recent research, including a study published in Nature Genetics, has drastically refined the structure of the tree. For that work, David and an international team of 42 scientists used complete Y-chromosome sequences from around the world to carry out the largest-ever study of genetic variation within the human Y chromosome (Poznik et al.). This research identified more than 65,000 Y-chromosome genetic variants, vastly increasing our understanding of the tree and setting a new standard for tracing male lineages through migrations that have occurred over the millennia of human history.


What’s Changing
Male customers on the new 23andMe website experience can expect a couple of changes to their paternal haplogroup assignment with this update, and female customers may see changes to the paternal haplogroup assignments of male relatives and friends in other parts of the website.

First, we have substantially updated our Y-chromosome tree to reflect the work of the International Society of Genetic Genealogy (as of January 4, 2016). In most cases, the updated haplogroup assignments are equivalent to previous assignments or differ only slightly. However, since much more is now known about the tree, we can provide more information about an individual haplogroup’s history and how it relates to others.

The second major update is a change to the naming system we use to report paternal haplogroups. Until recently, the convention was to use an often lengthy series of letters and numbers indicating the path of branches from the most recent common ancestor of all men to each haplogroup. The problem is that these names changed from year-to-year as the tree was refined, making it difficult to know from the name alone which haplogroup male customers actually carry.

To reduce confusion, we have moved to a system of shorter and more stable names. Each name uses a letter to identify the major branch of the tree and the name of a genetic marker unique to a specific haplogroup. For example, if we previously reported your paternal haplogroup as “Q1a3a,” we now report it as “Q-M3,” indicating that your Y-chromosome lineage belongs to a subgroup of haplogroup Q that bears the M3 marker. Because this new representation focuses on a specific informative marker associated with your haplogroup, it will be much more stable over time.


A small section of the updated Y-chromosome tree illustrating the marker-based haplogroup naming convention. The structure of the tree was aggregated from the literature by the International Society of Genetic Genealogy.

For more information on the changes coming to the haplogroups report, visit 23andMe’s customer care page, here.

yHaplo, a New Open-Source Research Tool
The paternal haplogroup update doesn’t end with the tree. As a member of the research team at 23andMe, Poznik has developed a new algorithm to rapidly and robustly identify Y-chromosome haplogroups in very large samples, and he has implemented the algorithm as the yHaplo software package. This software is very flexible; it runs on full Y-chromosome sequences and on smaller sets of genotyped markers. Furthermore, it is easy to incorporate updates as researchers around the world continue to gather data and learn more about the Y-chromosome tree.

At 23andMe, we’re using this software to provide paternal haplogroup assignments to our customers. As we believe the yHaplo software package can be an extremely useful tool to help drive research, we have made it available under a custom open-source software license for non-commercial research use. To learn more about yHaplo, read our white paper or head to the code repository!

    Hi Maryyamada,
    I’m not sure of the specifics, but that doesn’t sound like something we would do, unless there were privacy issues around your nephew’s account. I’m forwarding your comments to our customer care to see if they can address the issue.

    • maryyamada

      Yes, it is something they did do. They explained some while ago that because everything was still so new with the new rollout, they had to put my male DNA data on the back burner. I still don’t see it back. My nephew, who has an account with 23andMe (which I paid for), has absolutely no privacy issues on this matter. His name is David Muckey.

      • 23blog

        OK. I think I understand what you are saying, and I think this has to do with assigning a paternal haplogroup to you based on your nephews results. This may have to do with what version of the experience you and your nephew are on, but I will forward this to our customer care team and hopefully they can address it.

        • maryyamada

          Thank you; the matter should have been addressed by now, so I appreciate that it’s been picked up to be worked on. My father is dead; one of his sons had a son, and that is David Muckey.

        • 23blog

          Apologies that this is taking so long. I don’t know all the details, but I know that because customers have been transitioned at different times and in waves, it makes some of the sharing functions and interoperability difficult. I hope we’ll be able to address this for you soon.

      • Vicki Canon

        3 months later and I have the same problem.

  • 23blog

    It’s pretty straightforward to download your raw data. Here is a link to the instructions:
    Basically you navigate to the “tools” menu and then click on the “browse raw data.” Once there, you will see a “download” hyperlink. Click on it and follow the instructions.

    http://www.jogg.info/12/Athey.pdf). I understand that is new and evolving science, but, 23andMe, can you at least please tell us, I-M223 mutants, if we are descended from I1 or I2 ancestors?

    • 23blog

      “YCC” labels are in perpetual flux. Because they reflect the known
      structure of the tree, they change each time more information is
      discovered. At 23andMe, we rely on ISOGG as the authority on the current
      set of YCC-style haplogroup names. Please see their haplogroup I page:
      http://isogg.org/tree/ISOGG_HapgrpI.html. In it, they list the following
      line of descent for I-M223:
      I I-M170
      I2 I-M438
      I2a I-L460
      I2a2 I-M436
      I2a2a I-M223

    I was examined for Gynecomastia. I am male, 78 years of age and in good health. My height is about 5 ft. 11 inches and I weight about 185 pounds. I had painful breast and conditions described by Gynecomastia. However, I was told to stop drinking caffeinated beverages and eating chocolate products. The chest x-ray did not show I have pulmonary complication. I was told to have mammography after 3 weeks. I did.

    Mammography and ultrasound techniques showed I did not have breast cancer. The pain and the breast enlargement had reduced or disappeared.

    The physician told me although the problem is mostly observed among females; some males have genetic linked association with the problem. In these people, including myself, body chemistry treats the caffeinated products as estrogen analog. As we get older, the titer of testosterone naturally would decrease resulting in enhancement of the effect of coffee in those of us who have the genetic predisposition.

    Question: have your research identified the genome associated with Gynecomastia?
    Could you please pose this question to the research group for evaluation? Thank You.

    • 23blog

      Hi Michael,
      Sorry to hear about your condition. That is something that our researchers have not studied. I can ask the question to our research team, however.

  • 23blog

    Hi Isabella,
    No, but knowing your maternal haplogroup can help you when you are looking at your DNA Relative matches. This would allow you to determine which of those matches are on your maternal line. In that way you can at least narrow down the matches that are more likely on your paternal like. Your best bet is going to be some sort of triangulating to figure this information out. So for example if you know what your father’s ancestry was, and if it was distinct from what your mother’s ancestry was, this can also help in identifying DNA Relatives who are more likely on your father’s line.

  • 23blog

    Hi BJ,
    If would be unusual if you were not both on same branch of the paternal tree. There are cases, however, where an individual’s haplogroup assignment might not exactly match those reported to the individual’s parent or sibling. Apparent mismatches arise when more data are available for one member of the family than for another. So if you both have tested on different chips, or if there was a no-call in one of your tests for a relevant SNP.

    You can learn a little more about this here: https://customercare.23andme.com/hc/en-us/articles/202906920-Why-is-my-haplogroup-different-from-a-family-member-s-

  • 23blog

    No it does not. It just changes how we name the haplogroups and this was an attempt to make it more orderly and accurate.

    • Susan Solomon

      My understanding is that 23andme is now in a state of failing in terms of making it easy and simple to include a paternal line in a female customer’s account. My brother used to be my connection, now he isn’t actually connected, but still available as a source of the Y Haplogroup. We also lost our Parkinson’s data, rather a long time ago – am I correct on that? I can’t find mine anywhere. What is real good now is having the DNA printed out for each share so you can instantly see the genetic link. Yet overall I question the direction 23andme is going in terms of its internal goals. I feel, for instance, that using ‘Neanderthal’ DNA as part of this project should raise scientific eyebrows; many references to unproven ‘Neanderthal traits’ are intruded into this experience, which sort of lends 23andme a touch of Disney, but hey – maybe that’s exactly what the planners feel will work best.

      • 23blog

        Hi Susan, 23andMe is not failing, and our goals remain what they have been all along. Our mission has always been to help people access, understand and benefit from the human genome. What we can offer customers has changed because we operate in a regulated environment, but we are continually adding new reports, that focus on wellness, carrier status and trait reports. As for the issue with your brother’s paternal haplogroup, this has to do with customers who are sharing data being migrated to the new experience at different times. You should still be able to link to a male relative’s (your brother’s) paternal haplogroup and make it your own. (Here’s a link on how to do that: https://customercare.23andme.com/hc/en-us/articles/202906940-Linking-a-relative-s-paternal-haplogroup). If you have a problem with updating the assignment, you can contact our Customer Care team and they should be able to help. As for our past reports on certain health conditions, customers, like yourself, who had access to those reports are able to download them before migrating to the new experience. Here’s more information on getting access to the reports archive: https://customercare.23andme.com/hc/en-us/articles/219163167-How-to-access-and-share-the-reports-in-your-Reports-Archive

        • Susan Solomon

          I meant the idea of ‘failing’ in a routine, mild way – in that this linking thing seems to be a problem.

          However I’ve clicked on the link you sent in this email many times over, and it does not take me to a page that allows me to link my brother’s paternal haplogroup. The page with maternal and paternal circles does not allow me to click so as to share. I’d love to use it if it did work, and maybe I did something wrong.

        • 23blog

          OK, this may hinge on your brother and whether he is sharing back with you and or on the new experience. But I don’t know so I think it’s best that I let our Customer Care team try to help you out. Here’s a link to where to ask for help on this: https://customercare.23andme.com/hc/en-us/requests/new

  • 23blog

    Hi Truthseeker,
    The two calls are actually equivalent. M132 is a defining marker of the E1a haplogroup, hence “E-M132.”
    See, for example:
    The second row of that table is for haplogroup E-M132, whose YCC and ISOGG haplogroup names are E1a.
    Here is the line of descent from E:
    E E-M96
    E1 E-P147
    E1a E-M132

    Although E (E-M96) and E1 (E-P147) are common, E1a (E-M132), which descends from E1, is rare.

  • Mark Mitchell

    My father and I have gone from y-dna haplgroup R-L2 to R-PF6570. Which is very odd.

    1. Why did my father and I move up the tree from our previous designation of R1b1b2a1a2d3* (R-L2) to R1b1b2a1a2d (R-U152/PF6570)? This is less descriptive and less accurate than before.
    2. Why did you use R-PF6570 when R-U152 is much the better known designation throughout the genetic community? PF6570 is by far the least known of the 3 names used for this SNP. (S28 being the 2nd most common). I’ve been very involved in the U152 community for the last 4 years and had to look up what PF6570 was…almost no one in the genetic community uses this designation. If they do, very few people will know to what they are referring.
    3. For men that were “R1b1b2a1a2d” please change “R-PF6570” to “R-U152” and for all the former “R1b1b2a1a2d3” men at 23andme, please change them to “R-L2”.

    Thank you.

    • Sherril Stewart

      Same thing happened to my husband and his paternal cousin. R-L2 is a more common name. They are actually R-Z142 at FTDNA and R-CTS2819 at Yfull.

    • Rhonda Claus

      My son just had his done. He came back as R-M269 and R-PF6570. Any thoughts as to the best group to join? Where would I get the most info for this haplogroup? Thanks.

  • blitz

    You have to make sure that he “shares” his DNA with you. You can send him an invite to share. I had the same thing happen with my dad. After he accepted my invite he popped up as my closest relative match. If he shares with you and he still does not show up as a relative you may need to talk to your mom…

    • Melissa Lynn Collier

      He’s already sharing with me…I can see both his ancestry and health results and my ancestry results were updated. But the paternal haplogroup is still not updated. LOL there’s never been a question that he’s not my dad, I’m like the girl version of him.
      I’m wondering if there is a weird glitch that happened because we connected before his results came in…I gave him this as a Father’s Day present so that he could learn more about his ancestry.

      • 23blog

        OK Melissa,
        I’m going to forward this to someone with a little bit more knowledge on how to fix this. So expect to hear from our customer care team soon. Again my apologies for the difficulty.

      • E M

        Melissa…my whole life there was “never any question about who me (deceased when I was 4) father was…until I did genetic testing with my supposed half sister from him…and it came back no match. When I called my mom in total shock she blurted out in a reflex type way “the only other person it could be is “X”..” i was even more shocked..I was almost 30…she never..nobody ever gave ANY clue or hint that there was ever any chance the man I was told was my father was only 1 possible answer. It took another 18 months to get the info on the other “possible father” from my mom and when I saw his picture on FB it was shocking.. he was ale with blonde hair and blue eyes just like me…my entire life I was told I ws Italian, and the man I ws told was my dad had olive skin, black hair and dark eyes but my mom had brown hair and blue eyes so I figured I got it from her…it also made me realize she had to know my whole life when she looked at me and she secretly knew there were 2 possible fathera..I looked exactly like the 1 she didn’t want to be my father bc he was an alcoholic with post Vietnam metal problems nd the Italian man that passed when I was 4 ws an honorable and generous, amazing man with a great career as a police officer and president of his olive union…obviously the better “pick”…anyways I ended up talking to my supposedly new real dad’said other 4 kids (I had very little contact with my bio dad’s bc his craziness showed very quickly and way too severely for me to handle..looking learned his other 4 kids had no contact with him basically their entire lives.) My 4 siblings were amazing and loving and accepting and 1 brother agreed to do 3andme with me…which confirmed and connected us as half siblings. I have a friend who ws in the exact situation so you and at 1st her parents lied to her and kept saying there must be a computer issue but ultimately she spoke with someone at 23andme who entered thru all the steps to ensure sharing and all that with her and finally soured her the issue WAS NOT being caused by any books, settings issues or failures in the software rograms etc and they simply advised her to speak with her parents about other potential explanations. ( a nice way of telling her your dad isn’t connecting as a relative bc he isn’t a blood relative) eventually it was her dad that told her the truth not her mom ..(& yes her parents are still together, she’s 33) the situation was nothing scandalous it was a SD story the mom had been assaulted & they were both pro life so her and husband decided to raise the child/my friend as his ..they never imagined genetic testing would happen and they were afraid of traumatizing my friend by telling her the truth and causing potential identity issues…in the end it actually brought my friend and her dad closer than ever bc she was overwhelmed that he CHOSE her..that he loved her and raised her from birth under such traumatic circumstances & she told him she didn’t need the computer test to tell her about her father, she knew whof he was and how blessed she was. Ultimately she discovered 1 other thing that should have initially clued her in…when she went to relative connections on her and her dd’s pages and her daughter’s ..she had many that were connected s relatives to her that were NOT maternal connections and yet the male relatives had different haplogroups from her dad and when she went to her dad’s page non of the non maternilly connected relatives in her page showed as relatives of her dad’s. In the end that creeper her out and she turned off sharing or relatives ..etc bc she did not want to know anything about the man or his family etc who had assaulted her mother all those yrs ago. So, you may want to check relatives and see if you have the same issue…if there are a lot that are not in common with your dad’s list and they are not maternal connections….you def would ant to talk to your dad. Also in my friend’s case she literally is still JUST LIKE HER DAD (that raised her) same hobbies, same mannerisms, same quirks and they absolutely look like they are father daughter too. This is 1 reason 23andme warns customers that they could uncover info that is upsetting to them. I hope your case is just a settings issue but my advice if it turns out to be more…don’t let a test change the truth you’ve known in your life & don’t let it diminish the love or bond between you and your family. Everyone does the best they can with the resource they have and where they are in life when any given thing happens…we have to remember that and have compassion for the struggles of others. I pray you have a joyful and easy/peaceful resolution to your issue. There are support groups on FB for many have found similar things via genetic testing or they discover siblings they never knew of that were result of affairs, some that their mom’s gave up for adoption at some point etc…in case you need them just search FB groups. Good luck to you.

      • Johnny Panic

        I’m having the same issue. I can see my father’s info, etc, and it’s quite clear that he is indeed my father, but he is not showing up on my relatives list. Is there a lag time between the time the sharing info comes up and when the relatives list is updated?

        • 23blog

          Hi Johnny,
          That is odd. If you’re seeing him and he is sharing with you you should also have him on your DNA Relative list. I’m going to forward your note to our customer care to see if they can help you out.

  • 23blog

    You should be able to do that. First make sure that you’re sharing genomes with your brother. When you next go to your Paternal Line page you will see the option to set any share’s paternal haplogroup as your own.

  • Shanna Davis

    My father’s paternal haplogroup has not been updated and therefore neither has mine. Why? Have all of 23andme customers been reassigned yet?

  • joe aufmuth

    Thank you James! Your utility helped us break through to my wife’s maternal biological family! My wife had an FGS test at Familytreedna long ago and was assigned mtDNA haplogroup H27a. She tested at 23andMe, also long ago, and was assigned H. Your utility correctly assigned her H27. The 23andMe chips back then had known problems with mtDNA marker results. And now the “new” chip doesn’t even test for a defining marker of the haplogroup! However your utility assigned the correct haplogoup based on the markers the chip does test.

    I have also suggested to gedmatch that they incorporate your utility to their matching algorithms to improve their relationship projections.

    I can’t thank you enough for such an important utility! Well Done sir!

  • John Smith

    I’ve been told that I am R-M417. From my research however, this seems to be an ancient branch of the haplogroup, and as I understand it most modern Europeans in this group are some derivative of M417. Is it true that I am really M417 or is my data not clear enough to identify anything further?

  • jeffrey banner

    I was R1b1b2a1a2f* now I am M-529 it makes little sense to me as it seems less focused on a specific region. I thought the upgrades would fine tune things so I would know a specific area my haplogroup is from. Does anyone know a specific region this new M-529 is located for example Ireland ? and what part?

    • I just found your post again..& it seems we must run in the same Mobius Loop! ;) I was trying to find why 23/me had changed my son’s Haplogroup & found you out there on the Google, asking about the same thing…took me back to 23/me to their blog. Come to find out, I’d entered into some of the same disqus conversations you have, also. And, too…my mother’s Carter ancestoral patriarch, Issac Carter of Knox Co. Ky… has the same haplogroup designation. Some of his kin, seem to think they relate to the Carter/Johnson couple; but I don’t know, myself. I have several trees online, so if you’d like to compare notes, I would, too. I’ll try to find a way to msg you on 23/me..but I don’t always get my notifications. Anyway..my son is on there with his test & his name’s Lance McClellan. Maybe you can ck it out & see. I’ve had several inquiries from the two Hunter fellas on there, who seem to have hatched from eggs, but connect to both myself & my son’s dad..(mostly from Alabama & maybe from the Carolinas previously. I just recently found where Lance’s G-grandad’s buried out there, with several family members in a church cemetary..Blue Eye (Baptist)..Lincoln AL.

  • Vicki Canon

    I’m female, so I had my brother get his 23andMe kit done so I could see our father’s ancestry when we shared. It used to be available for me to see, but now it’s gone. I no longer have paternal information available to me, even though my brother and I are sharing. I just got an email from 23andMe confirming we are sharing all reports. Yet I don’t have any paternal line available? Where did the report go, and why can’t I see it?
    I also agree with some others that your new haplogroup names aren’t as accurate. I want to see the previous, much more accurate designation of my father, not the new short designation. (R-467).

      Give them another nudge.

    • Cynthia Posey

      Has this issue been corrected? My father and I were previously linked, but are no longer with the new version. Please assist.

  • Vicki Canon

    That’s what I want to know. The information was available on the old website and now it’s not available. My brother DNA was done here and I saw our paternal ancestry on the old site, but now I logged in to read it again and it’s gone, even though my brother is sharing all reports with me. I can’t see any information about our paternal ancestry, even though we’re sharing.

  • Vicki Canon

    Where is the section where you were able to list surnames, locations, etc., please? I would like to add to my information, but I can’t find the page on the new website.

  • Vicki Canon

    I’d like to know, too. Did they ever get back to you on this?

  • E M

    If you are female your son has his father’said paternal lineage. You would need a brother or father or a nephew of a brother that you share a father with to do the test from my understanding. My son is connected with me, my brother that I share a dad with and also my husband/his dad…my son shows the same paternal line as my husband NOT as my brother who I share a dad with/my half sibling. Hope this info helps.

    M529 is an alias of L21, On the old system, L21 corresponded to: R1b1b2a1a2f.

    • Clara Meredith

      Thank you for helping with that. I like to keep my notes clear and any changes recorded.

    • Clara Meredith

      Not trying to be a nuisance but when I updated my notes I noticed another P. Haplogroup that was missing my sons, he is now I-M253 I think he was I1 or I1*, Would you please help me with this?
      Oh and my cousin who is now R-L23 Whew…

  • Michele W.

    I totally agree. My brother is my FULL brother, so I would like my paternal haplogroup to be set, please.

  • 1bestdog

    I did a dna test for my father thru ancestry a few years ago before 23andme existed and he died before I could test him here….is there no way to add his results so I can learn my paternal hap?

    • 23blog

      Hello Ibestdog,
      We currently do not offer customers to upload data from other companies. And just a correction. 23andMe began offering direct to consumer genetic testing for several years before ancestry began offering their DNA services.

  • 23blog

    In the home page, go to “Reports” and in the drop down menu select “Ancestry.” Click on that and that will take you to Ancestry Page, you’ll see Haplogroups just under the Ancestry Composition. You can select that and you’ll go to the Haplogroups page.

    I paid for my brother’s kit so that I could link to his paternal haplogroup. It has been two years and I am still not linked and we are both sharing everything. I hope you guys resolve this soon as I bought the kit specifically for this reason.

  • LRB1972

    My children ALL have the same father, yet 23and me “with its new updates” is now giving me two different paternal haplogroups for my sons and I guess, because of that didn’t give my daughter one at all. Before the update they all had the same paternal haplogroup… How the hell does this happen? I am starting to lose faith in 23andme real fast.

  • LRB1972

    Paternal Haplogroup R-P311
    Paternal Haplogroup R-M412
    This is what they changed my sons’ paternal Haplogroup to. I can’t remember what they where before but they where the same.

    Trish, Your DNA relative matches will be from all branches of your tree, both the maternal and paternal sides. What is a little more difficult for women is identifying which side your matches are on.

    • Trish Berry

      Can you elaborate on that? Toward the bottom of the profile pages it says whether you’re connected on the maternal or paternal side, so I’m confused. Thanks so much.

      • 23blog

        We cannot easily identify paternal and maternal lines with women because they do not inherit a Y chromosome from their fathers. But the DNA Matches come from all branches of your family tree. So while we cannot determine if a match is on the maternal or paternal line, we include matches on both lines.

        • Trish Berry

          So IF I have a relative from my paternal side, they will be in the list of my matches? If so, can I determine this by process of elimination (that is, we will not have any of my maternal matches in common, and nothing in common in the maternal haplogroup)? Sorry for so many questions. Thank you so much!

        • 23blog

          Yes if you have a relative on the paternal side, they will show up in your matches. Determining which matches are on the maternal or paternal side is difficult, but yes you could use a process of elimination. You just need to be able to tap into additional information to help you make the determination.

        • Trish Berry

          What kind of additional information is that? Is it available on 23&Me?

        • 23blog

          If there is information you know that distinguishes your mom from your dad, such as their ancestry, you can look at that. In as a way to distinguish whether a match in on your maternal or paternal side. So for instance if you know that your biological mom has English Ancestry, but your biological father has Italian ancestry, than you can isolate matches with Italian ancestry. That can give you a good indication that those matches are likely on your father’s side. You could also look at geography or surnames, if you have some of that kind of information.

  • 23blog

    My apologies, but the steps to manually assign your paternal haplogroup are not working at the moment. We are attempting to update the feature so that customers like you can easily assign their known paternal haplogroup.

  • 23blog

    Hi Karen,
    Because women do not inherit a Y chromosome we cannot identify the paternal line, but your DNA Relative matches include those on both the paternal and maternal side. Using additional tools — surnames, ancestry, relatives in common, and geography for instance — could help you more easily narrow down which side of the family those matches are on.

    • Karen

      Well unfortunately my mom is passed away and I only know of my grandparents last names and my grandmothers maiden name. My grandfather’s mother was of the Cherokee tribe and because of the time’s she was afraid that people would know she were Indian so she took on the last name of Miller. I’m not even sure what his parents or my grandmother’s parents names are. I have suspicions of possible names but I’m not sure. And they didn’t have birth certificates when my grandfather was born.

  • Karen

    Unfortunately my mom has passed, and I only have one sister who has been teste and we’re waiting to see if she’s a full sister or half sister like we thought. If she turns out to be a full sibling then I’ll know who my father is, but otherwise i’m at a loss. I was told that with autosomal dna they can separate the paternal from the maternal lines. It’s a shame 23andme can’t do that.

  • FalconEddyMastering .

    I’m speculating that the reason for this change was to use a different haplogroup designation profile at 23andMe, as opposed to the standard haplogroup assignments for Y-chromosome participants. This might cause confusion if someone tried to give this new yHaplo assignment designation to someone outside of 23andMe for further research on their lineage if it is a proprietary designation.

  • Gwen Renner Stoller

    if my brother is on 23 and me, and we share information, why doesn’t the paternal side show up on mine?

  • L. Van Warren

    I was designated as R1b1b2a1a2f*, now I’m M-529.
    Here’s what I liked about the previous naming system. You could ask for each subclade as you read right to left, “At what epoch did that clade branch and where were they located? That is the most important knowledge embedded in the naming scheme. Using the M-529 variant provides NO such information. The long naming scheme was transparent and informative, the short one is opaque and much less useful.

    • 23blog

      L. Van Warren,
      You can still see the haplogroup tree and see where it branches off from the main. You have to go to the ancestry tab, then look at haplogroups and the scientific detail. Here is a link if you are signed in you should be able to see the tree: https://you.23andme.com/reports/haplogroups/details/

  • 23blog

    Hi Lisa,
    These haplogroup calls are consistent with one another; one is just a bit more granular than the other. It’s possible that the difference has to do with whether they tested on a different chips. One chip may be able to call more detail than the other. In this case the two haplogroups are consistent with each other. In particular, haplogroup R-M412 (also known as R-L51) is the immediate ancestor of haplogroup R-P311. This web page may help to illustrate: https://isogg.org/tree/ISOGG_HapgrpR.html; please search the page for “M412”. The page shows that people who carry the derived allele for the SNP named P311 also carry the derived allele for the SNP named L51 (also known as M412). So the different haplogroup calls between your sons is almost certainly due to one son not having a genotype call at a SNP equivalent to P311 and thereby receiving a slightly less
    granular haplogroup assignment.

  • Bobby Carroll

    The update sucks. My paternal haplogroup is way less specific now.

  • Kathy Allen

    In my maternal DNA it shows my french – German but not my Jewish side. My Grandfather’s(mother’s side) mother’s maiden name was Weiderhoft and came from Prussia. I called and asked a representative why it did not show up on my DNA chart. I wasn’t satisfied with the answer. Can anyone help answer?

  • Steve Rice

    Sadly I hate the new site, find it very confusing, don’t understand the apparent step back in quality and detail of the materials that used to be available and was not just available but entertaining to read! This front page is boring and hard to navigate. Not one thing in here about the history of Doggerland and any of that now in my history just a simple step back for rating and not even the one I expected to see considering I’ve been told all my life I was an O’Neill from the dynasty O’Neill’s only to be listed not as M343 which they agree as the old dynasty but now P311 WTF is that? and M-269 instead which I can’t tell is even related to M-343 or what it means but it appears to not only go against every story my Grandmother ever told me but completely turns around reports I got from the old site that we traced to Niall and seems to backpedal information now where I was listed simply as R1B1b2a1a now sub named its new incarnation for the time being anyway M-269 but at the to of the page it says Something 311 and no explanation to me as to why Haplogroup is listed twice but has that P311 at the top and M 269 in another place elsewhere? I ask you which is it? I find myself regretting telling my sister to join here as you have rearranged everything here to make it a holy nightmare to visit now compared to what you had! Bad enough to change all the haplogroups and subclades so much no one, not even the experts can keep up with it, but changing the way the pages work and info is outrageous! Not happy at all with the changes!

  • Reinhold

    Why is there no German DNA, when it is the largest ethnic group in Europe and the New World?
