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%.

R-L20: 176 samples. The common ancestor lived 4,000 years ago (3,700–4,400); the branch split off 4,000 years ago (3,700–4,500).
