The same branch on YFull #
YFull builds its tree from the same SNPs; the node is matched by name or by a shared SNP. TMRCA is when the common ancestor of all samples lived, formed is when the branch split from its parent. Intervals are 95%.
B4a1: 2,260 samples. The common foremother lived 26k years ago (22k–31k); the branch split off 30k years ago (25k–35k).
