Endeavor DNA offers confidential, accurate, fast, and affordable Y-STR paternal lineage testing services.
Y-STR testing determines whether two males share the same paternal lineage. The Y-STR paternal lineage DNA test is based on the fact that the Y chromosome is passed from father to son relatively unchanged through many generations. Only males can undergo Y-STR testing because females do not possess a Y chromosome.
Y-STR paternal lineage testing determines whether or not Y-STR markers are consistent, or not consistent, with the conclusion that the tested males may be related through a common male ancestor.
Y-STR analysis cannot distinguish a specific relationship between males who belong to the same paternal line. However, it is useful for excluding males from an alleged biological relationship.
