Duration: 2 hours

Overview

Principles, methods and applications of DNA-based prediction of human appearance traits for forensic and anthropological use with specific insights into eye, hair, and skin colour prediction from DNA.

Conventional forensic DNA analysis based on short tandem repeats (STRs) reflects an effective approach for human individual identification as long as the STR profile of the perpetrator is already available to the investigators, but fails if not. In such “suspect-less” cases, DNA testing aimed at predicting the physical appearance of the unknown sample donor is useful as it acts as an unbiased ‘molecular witness’ and can aid investigators by prioritizing suspect processing, corroborating eyewitness testimony, determining the relevance of a piece of evidence to a crime, and ultimately increase the ability to find unknown perpetrators of crimes who are unidentifiable via standard forensic DNA profiling. DNA-based prediction of appearance traits is also relevant in missing person cases and in anthropological cases for getting appearance information of deceased persons from their skeletal remains.
