Genetic Predisposition to Stray?

I've seen several other mentions of this study (all linking to the Washington Post article I am about to link to), but it's interesting enough to merit all of these mentions: Study Links Gene Variant in Men to Marital Discord

Basically, they found:

 The finding is striking because it not only links the gene variant -- which is present in two of every five men -- with the risk of marital discord and divorce, but also appears to predict whether women involved with these men are likely to say their partners are emotionally close and available, or distant and disagreeable. The presence of the gene variant, or allele, also seems predictive of whether men get married or live with women without getting married.
"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," said Hasse Walum, a behavioral geneticist at the Karolinska Institute in Stockholm who led the study. "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."

Interesting!  Biology is not destiny, but I smell a new bullet point in the list of mitigating circumstances in future divorce court proceedings!
