FTDNA Y-tree branch

R-Z2

Equivalent branches, the same kits: R-Z27 (5,353 kits, 4,000 years), R-Z345 (5,340 kits, 3,900 years)

R-Z2 is a branch of the FamilyTreeDNA Y tree with 5,353 kits that gave a country, counting all sub-branches. It is most common in these samples: Belgium (Flanders) (8.2% of kits), Barbados (8.1% of kits), Netherlands (6.9% of kits). The branch's common ancestor lived about 3,800 years ago: the FTDNA Discover estimate runs from 3,300 to 4,400 years ago. The oldest of the equivalent branches, R-Z27, split off about 4,000 years ago by Discover. YFull has 522 samples in this branch and dates its common ancestor to 3,900 years ago.

Where it is found #

Countries and regions given by the branch's carriers. “Share of branch” is the part of the branch's kits that belongs to the country. “Share of country” is the part of that country's kits that falls into the branch; it is computed only for countries with at least 50 kits.

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: 261 kits.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 360 distinct among 1,530 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-Z345: 522 samples. The common ancestor lived 3,900 years ago (3,500–4,300); the branch split off 3,900 years ago (3,500–4,300).
