A new study out of Sweden claims there is a direct link between a man's genes and his ability to remain faithful in marriage.
Researchers at the Karolinska Institute in Stockholm said men with a particular variant of gene called an allele – present in two of every five men – are at twice the risk of marital dysfunction and divorce. The study also showed women married to men with the allele scored lower on relationship satisfaction than those who are married to men without the gene.
"This is an interesting scientific finding, but it doesn't justify cheating on a spouse," Jenny Tyree, associate marriage analyst for Focus on the Family Action, said. "There's nothing impressive about a husband or wife who would use their DNA to cop out on their marriage commitment."
