===Alat uji DNA langsung oleh konsumen===
Di tahun 2000, [[Family Tree DNA]] adalah sebuah perusahaan pertama yang menyediakan alat pengujian DNA langsung oleh konsumen atau warga biasa. Pada awalnya mereka hanya menyediakan alat uji STR [[kromosom Y]] dengan sebelas penanda serta uji [[DNA mitokondria]] HVR1 dan bukan merupakan uji genealogi multigenerasi.<ref name=Belli>{{cite news|last=Belli|first=Anne|title=Moneymakers: Bennett Greenspan|url=http://www.chron.com/business/article/Moneymakers-Bennett-Greenspan-1657195.php|access-date=June 14, 2013|newspaper=Houston Chronicle|date=January 18, 2005|quote=Years of researching his family tree through records and documents revealed roots in Argentina, but he ran out of leads looking for his maternal great-grandfather. After hearing about new genetic testing at the University of Arizona, he persuaded a scientist there to test DNA samples from a known cousin in California and a suspected distant cousin in Buenos Aires. It was a match.
