FamilyTreeDNA is a company that offers DNA testing for ancestry and genealogy. It provides various tests, including autosomal DNA, Y-DNA, and mtDNA tests, to help individuals discover their heritage and connect with relatives. The company has three separate DNA databases, allowing users to trace their ancestry back several generations and find new matches. FamilyTreeDNA also offers group projects where users can collaborate with others to answer genealogical questions and break down brick walls that traditional genealogy alone cannot. The company frequently has sales and bundles to make their tests more affordable.
