What is a Y STR DNA Test?

Y DNA test is a testing option that helps to determine if two or more males share the same paternal lineage.  The Y chromosome is passed down relatively untouched from generation to generation from father to son. It should be noted that this will not differentiate men that are in the same paternal line. For example, if two men believe they are brothers that share the same biological father, a Y chromosome DNA test can be performed. If all the genetic markers match the results will reflect that the two men share the same paternal lineage. However, this means that the father’s brother(s) or father’s father could also be the father as they all come from the same male lineage.  If the profiles do not match, then they do not share the same biological father.
