About Genetic Genealogy

DNA Double Helix

Genetic genealogy is the use of DNA testing in combination with traditional genealogical and historical records. Genetic genealogy involves the use of genealogical DNA testing together with documentary evidence to infer the relationship between individuals.

Genealogical DNA testing first became available on a commercial basis in the year 2000 with the launch of Family Tree DNA and Oxford Ancestors.
