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%.

U4b1b1: 134 samples. The common foremother lived 3,600 years ago (3,500–3,800); the branch split off 5,500 years ago (3,800–7,700).
