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%.

K1a1a: 82 samples. The common foremother lived 4,700 years ago (4,400–5,000); the branch split off 5,900 years ago (4,900–7,000).
