Haplogroup A21 is a branch on the maternal tree of humanity with a likely origin in Tibet or the surrounding region. Its age has not been determined.

Academic information comes from three studies of peoples in or near Tibet. The first study found a member of the lineage in Chamdo, Tibet (Qin et al., 2010). Another comes from GenBank samples from an unpublished study of the Ladakh tribe (Sharma V et al., 2012). Finally, the branch was found in the Sherpa people (Kang et al., 2013).

Interestingly, the Geno 2 data set includes someone whose maternal origins are from Trinidad and Tobago. The a likely explanation is that their ancestor was one of the thousands of Indians taken into indentured service by the British. They became known as Indo-Trinidadians.


mtDNA Haplogroup A21 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 A21 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.
