What is Genetic Distance?

Genetic distance is a key measurement value when comparing the Y-DNA STR markers between Y-DNA profiles. It refers to the total difference in allele values of different genetic markers between two people.

The smaller the value of genetic distance for a given set of Y-DNA STR markers, the closer the two individuals are related, and the more recently they shared a common ancestor.
