Ancestry testing is a scientific method used to determine an individual's genetic heritage. By analyzing DNA samples, these tests can reveal information about a person's ethnic background and ancestral origins. Many people use ancestry testing to learn more about their family history and connect with distant relatives. These tests typically involve sending a saliva sample to a laboratory, where it is examined for specific genetic markers. Results can provide insights into various aspects of ancestry, including geographic regions and historical migrations. Ancestry testing has gained popularity through companies like AncestryDNA and 23andMe.
