DNA Can Reveal Facial Features

Introduction

It is already known that DNA can be used to track an individual’s ancestry. But it can also help in recreating one’s facial features, gender and race. Five per cent of genes control the differences in physical features. Their expression depends on the region, climate and social environment. By analysing genetic markers of different face shapes and the relationship between variations in face shapes and the effect of sex and genomic ancestry, it is possible to figure out how a person looks.
