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%.

J1c1b: 182 samples. The common foremother lived 4,400 years ago (4,100–4,800); the branch split off 5,800 years ago (5,300–6,200).
