Haplogroup X2 is a branch on the maternal tree of human kind. Its age is between 16,600 and 21,900 years (Behar et al., 2012b).

Age

Born between 16,600 an 21,900 years ago per Behar et al., 2012b, this branch dates to the last ice age.

Origin

Based on its modern distribution across Europe, North America, and and Middle East, this branch may originate between Western Eurasia and what it now the Middle East.

Modern Distribution

Branches that come from this one are spread throughout the world. However, those who belong to this branch but not a child branch have a separate distribution. In them, the most common locations are in Southern Europe and the Middle East.

mtDNA Haplogroup X2 Data Sources

GenBank Samples

GenBank is a database of genetic sequence data. It is run by the United States National Institute of Health. It serves as the main repository for mtDNA full sequence profiles. Samples come both from published academic literature and donations from genetic genealogy community members. In addition to GenBank samples, listings below may include other samples published but not submitted to GenBank such as those from the HapMap project.

Note: GenBank results currently use Phylotree build 16. I am working on changing results over to build 17.
