How Convincing is a Y-chromosome Profile Match Between Suspect and Crime Scene? (IMAGE)
Caption
A simplified illustration of a simulated population of males, with lines indicating father-son links. The suspected source of the DNA, whose profile matches that from the crime scene, is shown in red and other males with matching Y profiles, who are often close relatives, are yellow. The dashed line separates the last three generations, those further back in time will typically be already dead or otherwise unlikely to be of interest (depending on the circumstances of the crime).
