Haplogroup A2a4 is a Native Americas branch on the maternal tree of humanity. It is a young branch on the tree, and the woman who founded it lived in a Native North American population between very recent generations and 800 years ago. (Achilli et al., 2013)

Information on this lineage comes from one study. In it, the researchers found members of the line in the Navajo. They also found it in the general population of the Southwestern states, New Mexico and Arizona, and in Chihuahua, Mexico.

In the Geno 2 data set, participants from the line are from the United States and Colombia.


Achilli et al., 2013 links the spread of the line to the historic migration of Athabaskan language speakers from Canada. With this in mind, it is interesting that this young lineage has reached as far south as Colombia.

mtDNA Haplogroup A2a4 Phylotree History 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.
