Sub-branches #
Sub-branches that have their own page (50 kits or more). The bar is the kits in the sub-branch with its own sub-branches; the age is when its common foremother lived.
1 small sub-branch more without a page: 8 kits. On the branch itself, without a resolved sub-branch: 49 kits.
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%.
T2a1b: 194 samples. The common foremother lived 6,000 years ago (5,500–6,500); the branch split off 7,600 years ago (6,100–9,400).
