Haplogroup A3a is a Japanese branch on the maternal tree of humanity. Although its age has not been determined, it must be younger than its parent that was born between 2,200 and 11,300 years ago (Behar et al 2012b).

Available information on the line comes from three publications. Branch members in all three studies are from Japan.

There are members of this lineage in the Geno 2 dataset, but they have not entered their maternal origins information.

mtDNA Haplogroup A3a 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.
