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.
20 small sub-branches more without a page: 282 kits. On the branch itself, without a resolved sub-branch: 293 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%.
B2: 1,401 samples. The common foremother lived 15k years ago (15k–16k); the branch split off 20k years ago (20k–20k).
