Parent Branch: A2
Descendant branch(s): A2a1 A2a2 A2a3 A2a4 A2a5

Background

Haplogroup A2a is an Northeastern Siberian and Native Americas branch on the maternal tree of humanity.

Information on this line comes from five studies. In most cases, those tested are Eskimo type peoples. Two studies have found it in the Chukotka (Ingman et al., 2000 and Volodko et al., 2008). Others found it in the Chukchi (Derenko et al., 2007) and the Inuit (Gilbert et al., 2008). In contrast, Achilli et al., 2013 tested two members of the lineage in the Dogrib (Tłı̨chǫ) peoples who are Na Dane.

Interestingly, one person in the Geno 2 data set from this lineage traces their maternal origins to Denmark.

Achilli et al., 2013 suggests that the history of this line's migrations is complex with both an ancient and more recent bidirectional migrations between Siberia and far northern Canada.

Phylotree History

Phylotree.org is the maternal (mtDNA) tree of humanity. It is maintained by Dr. Mannis Van Oven. Each build is a major update to the tree. The current build is #17.

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.
