Guys: have you got a hot mom? Chances are your wife will be a looker, too. The same goes for daughters of hunky fathers.
Women tend to date guys that look like their fathers, and sons go for gals that look like their mothers, according to a new study of facial similarities between romantic partners and their parents. The paper is published this week in the Proceedings of the Royal Society B (DOI: 10.1098/rspb.2008.1021).
Tamas Bereczkei, a biologist at the University of Pecs, Hungary, and his colleagues mapped the faces of 67 young, long-term couples at their university, as well as each parent, measuring facial proportions such as the ratios of face length to width, nose length to face height, and mouth width to height.
