It was also the first to implement the use of autosomal DNA for ancestry testing, which other major companies (e.g., Ancestry, Family Tree DNA, and MyHeritage) now use. In 2007, 23andMe was the first company to offer a saliva-based direct-to-consumer genetic testing. They originally tested in partnership with the University of Arizona. They initially offered eleven-marker Y-Chromosome STR tests and HVR1 mitochondrial DNA tests.

In 2000, Family Tree DNA, founded by Bennett Greenspan and Max Blankfeld, was the first company dedicated to direct-to-consumer testing for genealogy research. Later, GeneTree returned to genetic testing for genealogy in conjunction with the Sorenson parent company and eventually was part of the assets acquired in the buyout of SMGF in 2012.

While in operation, SMGF provided free Y-chromosome and mitochondrial DNA tests to thousands. In fall 2001, GeneTree sold its assets to Salt Lake City-based Sorenson Molecular Genealogy Foundation (SMGF) which originated in 1999. However, it did not offer multi-generational genealogy tests. The first company to provide direct-to-consumer genetic DNA testing was the now defunct GeneTree.

3.1.4 Interpretation of Autosomal matches.

However, a Y-DNA test can only be taken by a male, as only males have a Y-chromosome. The mtDNA test can be taken by both males and females, because everyone inherits their mtDNA from their mother, as the mitochondrial DNA is located in the egg cell. Based on MtDNA and Y-DNA, a person's haplogroup(s) can be identified. MtDNA and Y-DNA tests are utilized to identify archeological cultures and migration paths of a person's ancestors along a strict mother's line or a strict father's line. However, they give considerably fewer DNA matches, if any (depending on the company doing the testing), since they are limited to relationships along a strict female line and a strict male line respectively. MtDNA and Y-DNA tests are much more objective. Autosomal tests are also used in estimating ethnic mix. Traditional genealogical research, and the sharing of family trees, is typically required for interpretation of the results. However, due to the random nature of which, and how much, DNA is inherited by each tested person from their common ancestors, precise relationship conclusions can only be made for close relations. The furthest degree of relationship is usually the "6th-cousin or further" level.

Each match will typically show an estimated degree of relatedness, i.e., a close family match, 1st-2nd cousins, 3rd-4th cousins, etc. Three principal types of genealogical DNA tests are available, with each looking at a different part of the genome and being useful for different types of genealogical research: autosomal (atDNA), mitochondrial (mtDNA), and Y-DNA.Īutosomal tests may result in a large number of DNA matches to both males and females who have also tested with the same company. Since different testing companies use different ethnic reference groups and different matching algorithms, ethnicity estimates for an individual vary between tests, sometimes dramatically. A genealogical DNA test is a DNA-based 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.
