A3

Summary

Age: 6,774.3 ± 4,573.5; CI=95% (Behar et al., 2012b)
Origin: Asia
Mutations: T2857C A8962G C9711T
FTDNA Tree: Link
Parent Branch: A
Descendant branch(s): A3a

Background

Haplogroup A3 is a branch on the maternal tree of human kind. The woman who founded this line lived between 2,200 and 11,300 years ago (Behar et al 2012b).

Published research includes five Japanese samples between three studies (Mikami et al., 2013, Nohira et al., 2009, and Ueno et al., 2009).

Geno 2 includes one person from the lineage whose maternal origin traces to Taiwan.

The age of the branch and its known origins indicate that one or more women in it may have taken part in the rice farming revolution.

mtDNA Haplogroup A3 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 A3 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.
