YFull

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%.

I-CTS616: 1,350 samples. The common ancestor lived 11k years ago (9,200–12k); the branch split off 12k years ago (11k–14k).
