FTDNA Y-tree branch

R-Z278

Equivalent branches, the same kits: R-Z297 (1,141 kits, 3,800 years), R-CTS2608 (1,140 kits, 3,700 years)

R-Z278 is a branch of the FamilyTreeDNA Y tree with 1,141 kits that gave a country, counting all sub-branches. It is most common in these samples: Peru (10% of kits), Spain (7.3% of kits), Argentina (7.0% of kits). The branch's common ancestor lived about 3,300 years ago: the FTDNA Discover estimate runs from 2,900 to 3,800 years ago. The oldest of the equivalent branches, R-Z297, split off about 3,800 years ago by Discover. YFull has 110 samples in this branch and dates its common ancestor to 4,400 years ago.

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.

5 small sub-branches more without a page: 48 kits. On the branch itself, without a resolved sub-branch: 387 kits.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 74 distinct among 230 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-Z297: 110 samples. The common ancestor lived 4,400 years ago (3,500–5,300); the branch split off 4,400 years ago (3,500–5,300).
