DNA Tribes

DNA Tribes is a personal genomics and biotechnology company based in Arlington, Virginia that allows individuals to have their genetic ancestry analyzed based on autosomal STR genetic markers developed by the FBI for individual identification in a forensic context. DNA Tribes also provides since 2011 a geographical "deep ancestry" analysis that can be performed based on genotype raw data from any of several SNP microarray tests. Autosomal DNA is inherited from both maternal and paternal ancestors. The methodology is a cheek swab kit which is delivered to the customer's home and then sealed and returned for analysis. Results are delivered to the customer via e-mail.
Sample populations
Currently, DNA Tribes has 920 sample populations collected by researchers from 305,000 individuals, including 673 populations classified as indigenous populations, and 195 populations classified as Diaspora populations, including multiple Jewish populations from Israel and the world Jewish Diaspora. DNA Tribes' sample population sizes range from 21 to 13,000.
The San Francisco Chronicle
A 2007 article on DNA ancestry testing companies said that "Several companies, including DNA Tribes of Arlington, Va., also offer a test that examines the DNA contribution of both parents. These tests are the most controversial because many scientists say there isn't enough data yet to get accurate results."
