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.
No sub-branch has its own page: only small branches lie below.
On the branch itself, without a resolved sub-branch: 1,072 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%.
K1a1b1a: 271 samples. The common foremother lived 1,900 years ago (1,800–2,000); the branch split off 2,500 years ago (2,200–2,700).
