I ran into this while looking for other information. Seems odd but you never know...



Cheating genes play large role in female infidelity; [LONDON 2ND EDITION]

"Abstract (Summary)
The Twin Research Unit at St Thomas's Hospital, London, carried out the study with 1,600 pairs of adult female twins, with an average age of 50, who completed a confidential questionnaire about their sexual history and attitudes. The scientists worked out the genetic component of infidelity and other traits by comparing the results for identical twins, all of whose genes are the same, with fraternal twins, who shared half their genes but grew up together.

Prof [Tim Spector] said a range of 50 to 100 genes were probably responsible for sexual behaviour. Genetic analysis of the twins suggested that genes on chromosomes 3, 7 and 20 might be involved but the association was not strong enough to identify any specific genes."

So the X and his recently divorced brother have cheat genes.

All this time I thought they were just careless and piggy.

I don't know about chromosomes genes 3,7, or 20. I like Levi's 501 myself.

I'm okay with that, just so long as nobody thinks it could be my responsibility.
