Five genes have been found to determine human facial shapes, as reported by researchers from the Netherlands, Germany, Canada, the United Kingdom, and Australia in the open-access journal PLoS Genetics. Monozygotic twins have almost identical faces and siblings usually have more similar faces than unrelated people, implying that genes play a major role in the appearance of the human face. However, almost nothing is known about the genes responsible for facial morphology in humans.
