Are you a heterosexual woman seeking a monogamous relationship? Have you ever wanted to genetically test a prospective partner for his ability to remain happily monogamous?
If so, don't pin your hopes on a study published last week in the Proceedings of the National Academy of Sciences. The study suggests that men with a particular gene variant are twice as likely as men without it to be bad at "pair bonding." Like so many genetic findings about complex human traits, if replicated, this finding would be of genuine interest. But it wouldn't be remotely enough for a new genetic test of infidelity.
