Police could soon identify a suspect’s eye colour from a single hair or
skin cell left at the crime scene. DNAPrint Genomics of Sarasota, Florida, is
patenting a test that searches DNA samples for genes that code for pigments in
the eye. The test spots the genetic variations known as single nucleotide
polymorphisms which correlate with different shades of eye colour. The company
also hopes to expand its crime-busting kit. A test using DNA samples to predict
hair colour is just around the corner, and they are also hoping to test for
height and weight, says chief executive Tony Frudakis.
