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-P78: 119 samples. The common ancestor lived 5,200 years ago (4,500–6,000); the branch split off 9,500 years ago (8,500–11k).
