FTDNA mt-tree branch

A2a

A2a is a branch of the FamilyTreeDNA mt tree with 55 kits that gave a country, counting all sub-branches. It is most common in these samples: Canada (First Nations) (2.2% of kits), United States (Native American) (1.0% of kits), Israel (0.9% of kits). The branch's common foremother lived about 4,900 years ago: the FTDNA Discover estimate runs from 4,400 to 5,500 years ago. YFull has 100 samples in this branch and dates its common foremother to 4,300 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.

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.

5 small sub-branches more without a page: 32 kits. On the branch itself, without a resolved sub-branch: 23 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%.

A2a: 100 samples. The common foremother lived 4,300 years ago (3,200–5,700); the branch split off 7,400 years ago (7,000–7,800).
