Haplogroup A11b is an Asian branch on the maternal tree of human kind. The woman who founded this line lived between 4,700 and 15,900 years ago (Behar et al 2012b).

Information on this line comes from three studies. The first study includes someone from the Naxi population (Hartmann et al., 2008). The second has one sample each from the Chamdo and Yunnan regions (Ji F et al., 2012). The last paper is medical, and demographic information simply states Chinese (Wang CY et al., 2011).

Geno 2 data does not have a member of this line.

The presence of this line in the Chamdo region is consistent with the line originating in the Tibetan Plateau like its parent. Further, the presence in the Naxi (Nakhi) population may be due to their trade with the Lhasa people along the Tea and Horse Caravan routes. The sample from Yunnan may then represent the spread of the lineage into southern China from Tibet.

mtDNA Haplogroup A11b 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 A11b 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.
