A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...

The genetic testing site 23andMe includes a Family Tree feature that automatically generates a tree based on DNA relatives in its database. It also allows customers to add other relatives to the tree.
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable.
It was founded by a group of surname DNA project administrators in 2005 to promote DNA testing for genealogy. It advocates the use of genetics in genealogical research, provides educational resources for genealogists interested in DNA testing, and facilitates networking among genetic genealogists.
