Haplogroup J2a2a is a branch on the maternal tree of human kind. Its age is between 8,900 and 16,800 years (Behar et al., 2012b).
mtDNA Haplogroup J2a2a Phylotree History
Phylotree.org 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 J2a2a Data Sources
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 results over to build 17.
