YFull

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.

Ashkenazi Jews (Yiddish): 12% of samples (4 of 34)

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: 322 kits.

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%.

K2a2: 114 samples. The common foremother lived 4,100 years ago (2,100–7,200); the branch split off 5,700 years ago (5,300–6,100).
