The DNA on the Y chromosome changes very little over time, so a man can trace his family ancestry through genetic testing of the Y chromosome. The chromosome is tested for markers in specific locations on the Y chromosome. These markers are numbered 1-33, or 1-46, and a corresponding number is assigned to each marker.
