Autosomal DNA testing for family history 11.png

Autosomal DNA testing is the most common form of DNA testing for family history. That’s because it’s affordable AND it gives you insight into BOTH sides of your family tree—your mother’s side and your father’s side.

The autosomal DNA is a great place to start your DNA journey. This is the kind of DNA test you purchase from AncestryDNA, 23andMe, Living DNA and MyHeritage DNA—and one of the kinds of tests you can purchase from Family Tree DNA. Your test results provide you with ancestral ethnicity percentages and a list of your genetic relatives who have tested at that company.
