How does DNA Tribes STR testing compare to autosomal tests that use hundreds of thousands of SNP markers?
The primary benefit of STR rather than SNP testing is the availability of reference data. DNA Tribes tests industry standard autosomal STR systems, which allow the identification of a person’s DNA profile not shared with any other person. Because these STRs have been tested for use in court systems around the world, they allow DNA Tribes to perform the most thorough comparison of a person’s own DNA profile to over 1,000 ethnic groups around the world. At present, SNP test does not yet match the geographical detail of DNA Tribes autosomal STR analysis.
