Haplogroup A2am is a branch on the maternal tree of humanity. It is a Native American branch that comes from a line of women who crossed the land bridge to the Americas at least 13,000 years ago. Its age has not been determined. We know though that it must be younger than that land bridge crossing.
mtDNA Haplogroup A2am 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.
|16||A2am||T6253C T15229C G15314A||Released 19 Feb 2014|
|17||A2am||T6253C T15229C G15314A||Released 18 Feb 2016|
mtDNA Haplogroup A2am Data Sources
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.
