In the latest tale of mice and men, researchers compared men and voles, a mouse-like varmint. The study found a gene variant, or allele, present in cheating voles also was present in two of every five men.
According to the study's conclusions, those men with the cheating allele were more prone to marital dysfunction and more likely to get divorced. Men with two copies of the allele were twice as likely as a man without the allele.
The Karolinska Institute in Stockholm, Sweden, studied the genetics of cheating. Researchers there said the cheating allele regulates the activity of a hormone in the brain that can affect a man's attitudes toward fidelity and monogamy.
If a man lacks the gene variant they're more likely to be a devoted mate, researchers said.

Why some men cheat – genetic link to relationship difficulties
September 4, 2008 Comedian Robin Williams once defined the key issue of fidelity as being that men had a brain and a penis and only enough blood to run one at a time. We all know some guys are faithful, and some are not, but until now, it all appeared random behaviour. Now new research suggests…
