  • Different Results on a Brother's Haplogroup

    A friend took a Y DNA test with Familytreedna and his Haplogroup was E-M2. His brother took a Y DNA test with 23 and Me. His Haplogroup was E-M96. They are believed to be full siblings. Should their Haplogroup numbers have been identical even though they tested with different companies?

    Haplogroup assignments depend on the SNPs tested. Each are just tested to a different subclade level.

    Both are only partial haplogroup assignments,
    SNP M96 (E-M96) is the defining SNP for Haplogroup E (Parent Branch of Haplogroup E)
    SNP M2 (E-M2) is the defining SNP for a subclade branch of E.

    E-M2 is also E-M96 , just a deeper subclade branch.
    E-M96 > E-P147 > E-P177 > E-V38 > E-M2

    If they both had different Haplogroup other the E, then one would question.

      Thank You!!!

      Thank you so much for your response. I definitely appreciate it!!

        At this point FTDNA has only predicted the Haplogroup. 23andMe has done minimal SNP testing to determine a Haplogroup and therefore assigned a downstream Haplogroup.

          You could encourage the E-M2 brother who tested at FT to join the E1b1a - V38 project. It is really exceptional. The administrator participates actively in the ongoing discussion/questions/comments section.

            Considering both companies reported that they belong to some level of the E haplogroup I would rest assured that they are related.
