Haplogroup U6 is a branch on the maternal tree of human kind. Its age is between 31,400 and 43,100 years (Behar et al., 2012b).

National Geographic Geno 2.0 Text

Haplogroup: U6
Age: 24,970 ± 8,370 Years Ago
Origin: West Asia
Blurb: This branch in your maternal ancestry took place in West Asia around 25,000 years ago. Some from this group traveled a southern route to North Africa. There they constructed huts to withstand the harsh climates of the Upper Paleolithic period and the dry conditions of the last glacial maximum. They used relatively advanced tools of stone, bone, and ivory. Jewelry, carvings, and intricate, colorful rock paintings bear witness to their surprisingly advanced culture during the last glacial age.

After the last glacial maximum, population expansions led people across the Strait of Gibraltar for the first time, which allowed for some gene flow between North Africa and the western Mediterranean. This bi-directional movement led some from this lineage along the western coast of Europe. Thus, some from this line are present in Western Europe.


Today, this lineage is present in Tunisia (9 percent) and Spain (4 percent). It is between 1 and 2 percent of maternal lineages in France, Ethiopia, Portugal, the Netherlands, and Italy. It is also part of some Jewish Diaspora groups, such as Ashkenazi Jews.

mtDNA Haplogroup U6 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.
