Until now, DNA left at the scene of a crime only proves useful if it is already stored in a database and can be matched to a suspect. But a team of forensic experts have devised a way to recreate the face of a person, including eye and skin colour, using as little as 50 picograms (0.05 nanograms) of extracted DNA. Called DNA phenotyping, the tests also determine the person’s ancestry, if they have freckles and can be used to match with distant relatives. DNA phenotyping is the prediction of physical appearance from DNA and is a technique being pioneered by Virginia-based Parabon Nanolabs. The technology can be used to generate leads in criminal cases where there are no suspects or database hits, or to help identify remains, for example. Samples can be potentially taken from as little as a fingerprint. Parabon’s Snapshot Forensic system is said to be able to accurately predict genetic ancestry, eye colour, hair colour, skin colour, freckling, and face shape in individuals from any ethnic background. Each prediction is presented with a ‘measure of confidence’. As an example, the test can say a person has green eyes with 61 per cent confidence, green or blue with […]
