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%.

I-FGC16678: 301 samples. The common ancestor lived 3,000 years ago (2,700–3,400); the branch split off 3,400 years ago (2,900–4,000).
