You're Nice, He's a Jerk - is it because of your Oxycotin receptor genes?

A study published in PNAS: Thin-slicing study of the oxytocin receptor (OXTR) gene and the evaluation and expression of the prosocial disposition indicates that individual differences in social behavior are correlated with variants of their Oxycotin receptor genes. Previously, another study in PNAS: Oxytocin receptor gene (OXTR) is related to psychological resources indicated that variation in this gene was also related to other personality traits. Forget about horoscopes, find out whether your potential mate has the A or G allele of the oxytocin receptor (OXTR) SNP rs53576!
Oxytocin is the "love hormone" associated with maternal and sexual behavior.
