X2b4
X2b4 is a branch of the FamilyTreeDNA mt tree with 170 kits that gave a country, counting all sub-branches. It is most common in these samples: France (0.8% of kits), Jamaica (0.7% of kits), Slovakia (0.7% of kits). FTDNA Discover publishes no age for this branch; YFull's, when it has one, is below. YFull has 59 samples in this branch and dates its common foremother to 800 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.
On the branch itself, without a resolved sub-branch: 119 kits.
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%.
X2b4: 59 samples. The common foremother lived 800 years ago (700–800); the branch split off 1,000 years ago (1,000–1,000).
