Genealogical DNA test - Wikipedia, the free encyclopedia

Genealogical DNA test - Wikipedia, the free encyclopedia: "Genealogical DNA tests allow one to identify their recent and far distant ethnic and geographic origins. Most commonly, one uses Y chromosome (Y-DNA) testing and mitochondrial DNA (mtDNA) testing. Y-DNA & mtDNA tests are by far the most common and often people refer to them as the only genealogical DNA tests. However, additional tests are available for distant and recent ethnic origins."
