Forensic Test Can Determine Person's Eye and Hair Color

An anonymous reader writes: A forensic test that has been developed to help police nab perpetrators of crimes can predict a suspect's eye color, hair color, and ethnic origin. The test's ability and the science behind it has been outlined in Forensic Science International: Genetics. Developed by Susan Walsh and other researchers from the Netherlands, Greece, and Poland, the test uses phenotypes from DNA to determine a suspect's eye color, hair color, or place of ethnic origin.
