Descendant branch(s):


Haplogroup A1a1 is a branch on the maternal tree of humanity. It is between 1,500 and 8,300 years old (Behar et al 2012b).

This lineage has been found in two published studies. The first is medical (Hartmann et al., 2008). The second found members in the Kizhi and the Buryat of Siberia (Derenko et al., 2007).

The Geno 2 dataset does not currently include members of this lineage.

Considering the origins of available samples and those of the parent branch, this lineage may have been part of a westward migration from East Asia. Alternatively, it may have been born in its current Siberian homeland.

It is worth noting that prior to Phylotree build 16 this lineage was known in published literature as A4a1a.

mtDNA Haplogroup A1a1 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.

mtDNA Haplogroup A1a1 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.
