Identical twin DNA no longer indistinguishable

It’s such a great conceit for a crime show: guy commits murder; guy denies it; turns out it was guy’s identical twin all along; everyone is happy (except murdered dude).

Though identical (or “monozygotic”) twins account for only one birth in every three thousand, geneticists have been baffled attempting to find ways to tell twins apart forensically; regular DNA fingerprinting doesn’t show any difference between the two individuals. This, obviously, can create some complications when it comes to forensic evidence and even paternity testing.

But a new study published in Forensic Science International: Genetics shows that Eurofins, a German company specializing in forensic genetics, has found a very specific way to differentiate between identical twins.
