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.

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 ancestor lived.

3 small sub-branches more without a page: 42 kits. On the branch itself, without a resolved sub-branch: 1 kit.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 86 distinct among 316 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.

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%.

R-Z338: 103 samples. The common ancestor lived 2,500 years ago (2,100–2,900); the branch split off 2,900 years ago (2,400–3,400).
