FTDNA Y-tree branch

I-CTS4002

Equivalent branches, the same kits: I-CTS10936 (2,786 kits, 5,900 years), I-S19848 (2,779 kits, 5,800 years)

I-CTS4002 is a branch of the FamilyTreeDNA Y tree with 2,786 kits that gave a country, counting all sub-branches. Almost all of its kits sit in a single sub-branch, I-CTS10228, so this branch gets no conclusions of its own. It is most common in these samples: Bosnia and Herzegovina (31% of kits), Croatia (26% of kits), Montenegro (21% of kits). The branch's common ancestor lived about 5,600 years ago: the FTDNA Discover estimate runs from 4,900 to 6,400 years ago. The oldest of the equivalent branches, I-CTS10936, split off about 5,900 years ago by Discover. YFull has 1,145 samples in this branch and dates its common ancestor to 5,500 years ago.

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: 35 kits. On the branch itself, without a resolved sub-branch: 28 kits.

Surnames #

Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 58 distinct among 138 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%.

I-CTS10936: 1,145 samples. The common ancestor lived 5,500 years ago (4,500–6,500); the branch split off 6,400 years ago (5,300–7,600).
