Police take step toward creating ‘wanted’ posters from DNA, thanks to new study

ancestryIt’s no secret that there is a genetic aspect to our looks ‒ how many times have you heard you look like a relative? It turns out that specific genetic mutations are responsible for many facial features, from nose size to face width, a new study finds.
Researchers led by John Shaffer, assistant professor of human genetics at the University of Pittsburgh, analyzed the genomes of more than 3,000 people with European ancestry. The subjects then had 3D scans done of their faces, which the scientists used to focus on 20 different facial traits, including measurements and sizes across different areas of the face.
