An Ancestry Testing Company is Only as Good as Its Database

DNA testing companies rely on genetic information databases to provide clear and reliable information about your ancestry. These databases typically contain both publicly available genetic information and genetic data from other users of a company.

The larger and more comprehensive the database of testing services, the better. A larger genetic database allows a company to more accurately trace your genes to a specific ethnic group or assist you in finding distant relatives. That's one of the reasons why popular ancestry testing companies like MyHeritage and LivingDNA make so much sense. Millions of users have already tested their ancestry and contributed genetic information to these companies. This means you'll have more detailed information about your ancestors.
