Most common among these peoples #
From YFull samples that gave a mother tongue: the part of a people's samples that falls into this branch. Peoples with at least 3 samples in the branch are listed.
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: 38 kits. On the branch itself, without a resolved sub-branch: 1 kit.
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%.
T2a: 546 samples. The common foremother lived 9,600 years ago (6,700–14k); the branch split off 12k years ago (12k–13k).
