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%.

J-Z18271: 142 samples. The common ancestor lived 2,800 years ago (2,400–3,300); the branch split off 2,800 years ago (2,300–3,300).
