Forensic scientists a step closer to predicting a suspect's hair colour from crime scene DNA alone
Forensic scientists are a step closer to predicting the colour of a suspect's hair from their DNA alone after the discovery of more than 100 new genes that influence the shade of a person's locks.
A test based on the new genetic markers was 10-20% more accurate than existing forensic tests and was most reliable for red or black hair, with brown or blond hair proving harder to predict, researchers said.
