Haplogroup W4a is a branch on the maternal tree of human kind. Its age is between 5,300 and 13,900 years (Behar et al., 2012b).

National Geographic Geno 2.0 Text

Haplogroup: W4a
Age: To Be Determined
Origin: West Asia
Blurb: This point in your ancestors’ journey began in West Asia. Groups containing this lineage traveled west toward the Mediterranean and then north into Europe. They very likely traveled in groups alongside their more distant cousins from the ancestral lineage, as both lines share similar distributions in modern populations.

Today, this lineage is most common in Northern Ireland, where it is 2 percent of the population, and in Wales where it is 1 percent of the population. It is notably less common in the rest of the British Isles. This lineage is also 1 percent of maternal lineages in Romania and the Czech Republic.

mtDNA Haplogroup W4a 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.
