Is there a possibility that there is a person with exactly the same DNA as me?
Recently, in a crime stoppers tv show, they talked about a semen sample the police had, of a murderer.
They stated that if they caught him and he’d appear in court, the prosecutors would say that there would be a very slim chance (one in half a billion, if I am correct) that not he but someone else killed the victim.
Does this mean that there are a possible half a dozen to a dozen other humans (or rebbels) with identical DNAs?
