Ethiopia- "I was told The Father of My Daughter his is not her daddy in DNA test" Yeselam Gebeta
A genealogical DNA test is a DNA-based test which looks at specific locations of a person's genome in order to determine ancestral ethnicity and genealogical relationships. Results give information about ethnic groups the test subject may be descended from and about other individuals that they may be related to. Three principal types of genealogical DNA tests are available, with each looking at a different part of the genome and useful for different types of genealogical research: autosomal, mitochondrial, and Y. In general, genealogical DNA tests do not give information about medical conditions or diseases. The first company to provide direct-to-consumer genetic DNA testing was the now defunct GeneTree. However, it did not offer multi-generational genealogy tests. In fall 2001, GeneTree sold its assets to Salt Lake City-based Sorenson Molecular Genealogy Foundation(SMGF) which originated in 1999.While in operation, SMGF provided free Y-Chromosome and mitochondrial DNA tests to thousandsLater, GeneTree returned to genetic testing for genealogy in conjunction with the Sorenson parent company and eventually was part of the assets acquired in the Ancestry.com buyout of SMGF. 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. They initially offered eleven marker Y-Chromosome STR tests and HVR1 mitochondrial DNA tests. They originally tested in partnership with the University of Arizona. In 2007, 23andMe was the first company to offer a saliva-based direct-to-consumer genetic testing.It was also the first to implement using autosomal DNA for ancestry testing, which all other major companies now use. In 2018 it was estimated that over 12 million people had their DNA tested for genealogical purposes, most of whom were in the USA.
