(Shutterstock) (Newser) – DNA evidence may soon be able to give detectives one more clue about a suspect: hair color. Dutch researchers say they've figured out the markers to determine red or black hair with 90% accuracy, and brown or blond hair with 80% accuracy, reports LiveScience. It's "a major breakthrough because, so far, only red hair color, which is rare, could be estimated from DNA," says the head of forensic molecular biology at the Erasmus Medical Center in the Netherlands. The study is in the journal Human Genetics.
