The test analyzes a person’s genome at over 700,000 marker locations and provides customers with an easy and affordable way to help explore their ancestral background and discover their family’s past. AncestryDNA also cross-references an extensive worldwide database of DNA samples with documented family histories. This reference collection, acquired by the Sorenson Molecular Genealogy Foundation, includes samples from more than 100 countries on six continents, which enables new levels of discovery about people’s family backgrounds.
