  • making sense of y37 results

    I got my Y37 results. It says that my paternal haplogroup is R-M269. Googling says (on wikipedia) that is the same as R1b1a2. But... my 23andme results say that it is R1b1b2a1a2f*. So, obviously this doesn't make sense to a novice.

    Why are there two different naming systems for haplogroups? Which is/should be the correct one to use?

    Why are the results different? FTDNA says R1 B1 A2, but 23andme says R1 B1 B2 ...

    Sorry. Can someone explain what this means and why the results are different?

    R1b1b2a1a2f* is actually R L-21 which is a subclade to R1b1a2.

    the 37 marker tests just estimates your haplogroup,
    while 23andme tests some SNPs which is why they designated you R1b1b2a1a2f* at 23andme.

    you should join the R L21 project here at FTDNA. Let them know you are classified as R1b1b2a1a2f* at 23andme and they will accept you in the group.

      FTDNA and 23andme use different yDNA trees. Not sure which each of the current versions are being used to date.

      see post 2 in the following

        jova99 is correct. R1b1b2a1a2f* at 23andme is L21 and lmccourry should join the L21 DNA project at

        23andme uses the 2009 ISOGG tree which has R1b1b2a1a2f* as L21.

        FTDNA does not test SNPs for the Y37 test so it is just an estimation of the SNP based on the STRs.

        The L21 admin would be able to guide lmccourry as to what the next test he should get is. If there is a close match or STR signature then he could help him save money on SNP testing.
