Haplogroup W3a1a is a branch on the maternal tree of human kind. Its age is between 8,100 and 13,000 years (Behar et al., 2012b).

National Geographic Geno 2.0 Text

Haplogroup: W3a1a
Age: To Be Determined
Origin: To Be Determined
Blurb: This branch of your maternal lineage was founded by a woman in a group traveling from their homeland in West Asia toward Europe. However, it is not yet clear at what point in that journey she was born.

Today, this rare lineage is present at trace frequencies of less than 1 percent in Europe.

mtDNA Haplogroup W3a1a 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.
