  • It's In His Genes

    Scientists have discovered what's been labeled the "cheating gene," which can be associated with relationship discord. Certain men have a gene variant (also known as an allele) that influences their brain activity and makes bonding difficult. According to Hasse Walum, a behavioral geneticist at Karolinska Institute in Stockholm who led the study that found this variant, "Men with two copies of the allele had twice the risk of experiencing marital dysfunction, with a threat of divorce during the last year, compared to men carrying one or no copies. … Women married to men with one or two copies of the allele scored lower on average on how satisfied they were with the relationship compared to women married to men with no copies." But hope for a monogamous relationship is not entirely lost for those with this gene. "The bottom line is that men have to learn to overcome temptation and biological impulses in order to stay faithful," says Wanis.
