If there is one thing that we can say is truly unique to each of us then surely it is our DNA, right? Well, not always. Believe it or not, some people have more than one DNA profile. In this episode, Dom explores how an individual can acquire a second DNA profile, be born with two DNA profiles and the effects these rare cases are having on criminal forensics.
