Background

Haplogroup K2a is a branch on the maternal tree of human kind. Its age is between 6,800 and 11,400 years (Behar et al., 2012b).

National Geographic Geno 2.0 Text

Haplogroup: K2a
Age: 14,100 ± 6,700 Years Ago
Origin: West Asia
Blurb: This lineage was born in West Asia. Different groups containing women from this lineage spread across to Anatolia and eventually to Europe.

Today, this lineage is present in the United Arab Emirates (8 percent), Wales (5 percent), Northern Ireland (5 percent), Spain (3 percent), the Netherlands (1 to 2 percent), and France (1 to 2 percent). A subtype of this lineage is part of Jewish Diaspora population groups. This particular subtype may be responsible for the frequency of this lineage in modern Mexico, where it is 1 to 2 percent of maternal lineages.

mtDNA Haplogroup K2a 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 resuts over to build 17.

Geno 2.0 Data

Data from Geno 2.0 is derived from the The National Geographic Society’s Genographic Project — the DAR. The Hg ID is specific to this site and is used to protect the identities of those who take part in Genographic research. Birth Country, Mother's Birth Country, and Maternal Grandmother's Birth Country have been normalized from DAR database fields. The Maternal Origin is determined based on the three previous fields.

Note: Geno 2.0 results currently use Phylotree build 16. I am working on changing resuts over to build 17.
