Can a Woman Take This Test?

Yes, both women and men can use AncestryDNA since they all carry the DNA that is being tested. In fact, men and women are tested in the same way for the same number of markers. Unlike some other DNA tests, which only analyze the Y-chromosome (and can only be taken by a male to look at your direct paternal lineage) or mitochondrial DNA (can be taken by a male or female but only looks at your direct maternal lineage), AncestryDNA looks at a person's entire genome at over 700,000 locations.
