    Yfull: Shared SNPs vs Assumed Shared SNPs?

    Hi all,

    What is the difference between shared SNPs and assumed shared SNPs?

    Would I be correct to assume shared SNPs are more stable as assumed SNPs may not be definite?

    Using this reasoning(despite a TMRCA of 2000-2300ypb between us), my closest Yfull match that has the most shared SNPs is an Adyghe/Circassian.

    I also have another Adyghe(Shapsug) match(not as close as the first) whom is YP263*.

    Assumed shared SNPs are not reported in one of the results. Since they are part of a block of equivalent SNPs they are all assumed to be positive until shown otherwise. For any assumed SNPs one should try to get results for them from YSEQ.NET. A negative result creates a new haplogroup node.
