Phenotyping eye color

WebForensic DNA phenotyping (FDP) is an emerging technology that seeks to make probabilistic inferences regarding a person’s observable characteristics (“phenotype”) from DNA. The aim is to aid criminal investigations by helping to identify unknown suspected perpetrators, or to help with non-criminal missing persons cases.
