A1

Summary

Age: 12,987.6 ± 5,404.2; CI=95% (Behar et al., 2012b)
Origin: Asia
Mutations: G1442A
Parent Branch: A
Descendant branch(s): A1a

Background

Haplogroup A1 is a branch on the maternal tree of humanity. It was born between 7,600 and 18,400 years ago (Behar et al., 2012b).

Most members of the lineage belong to one of its daughter branches. However, there is one example in published research from Japan that does not (Bilal et al., 2008).

The one person in the Geno 2 dataset who belongs to this line but not a daughter branch has not included demographic information.

It is worth noting that prior to Phylotree build 16 this lineage was known as A4a.

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.

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.
