I’ve had my DNA tested through other genetic testing sites like Ancestry.com and 23andMe. How do my Genographic Project results differ from theirs, and why?
The Genographic Project is a research project of the National Geographic Society, which encompasses work carried out by our scientific team to elucidate new patterns of human migration, as well as public testing through the participation kits. Our testing focuses on deep ancestry from an anthropological perspective. It is not primarily a genealogy testing service, such as that offered by Ancestry.com, although you do have the option of seeing how you are related to other participants in the Our Story section. 23andMe is primarily a medically focused testing company, examining markers that are associated with disease risk. While they do offer some insights into ancestry, that is not their primary focus. The genetic technology we use for our testing is a custom-designed genotyping chip optimized for the study of ancestry, with far more Y-chromosome and mtDNA markers than are available with any other test. Our autosomal markers are similarly optimized for inferring ancestry, rather than medical testing, and we feel that it is the best technology available for this purpose.
