Haplogroup T2b is a branch on the maternal tree of human kind. Its age is between 8,500 and 11,700 years (Behar et al., 2012b).

National Geographic Geno 2.0 Text

Haplogroup: T2b
Age: 8,400 ± 3,150 Years Ago
Origin: West Asia
Blurb: Born at the beginning of the Neolithic Revolution, this lineage likely originated in West Asia.

Today, it is present at the highest frequencies in Croatia (12 percent), Tunisia (9 percent), and Greece (5 percent). In Iran, it is about 4 percent of maternal lineages, and it is about 3 percent of maternal lineages in Armenia. It is also part of some Jewish Diaspora population groups. It is about 7 percent of the population in Bulgaria. Elsewhere in Europe, this line is around 6 percent of the population in Germany and around 5 percent of the population in the British Isles, France, and the Netherlands.

mtDNA Haplogroup T2b Phylotree History 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 T2b 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.
