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%.

T2b4: 351 samples. The common foremother lived 2,500 years ago (1,500–3,700); the branch split off 4,100 years ago (4,000–4,200).
