Scientists are trying to figure out a way to create sketched DNA mugshots from a tiny little piece of DNA. Apparently your DNA reveals a lot about what you look like, and not only your genetic makeup. A tiny piece of DNA can determine eye colour and hair colour, but it can also trace your ancestry to a particular region (which, according to scientists, can give clues about what you look like).

The scientists used an old piece of DNA to determine what a prehistoric man looked like, so why couldn't DNA mugshots work for today's criminals?
