DNA evidence often isn’t as watertight as many people think. Sensitive techniques developed over the past 20 years mean that police can now detect minute traces of DNA at a crime scene or on a piece of evidence. But traces from a perpetrator are often mixed with those from many other people that have been transferred to the sample site, for example via a handshake. And this problem has led to people being wrongly convicted. Scientists have developed algorithms to separate this DNA soup and to measure the relative amounts of each person’s DNA in a sample. These “probabilsitic genotyping”…
