If you want to know if your husband will cheat, you may want to take a close look at your father-in-law.

According to a study, male infidelity runs in the family, which will come as no surprise to the wives of womanising celebrities who had cheating fathers such as Tiger Woods and Ryan Giggs.

The study found that men were more likely to stray if their fathers had been unfaithful when they were growing up. Researcher Jan Havlicek said daughters were not affected in the same way by their mothers’ infidelity.

The Czech scientists from Charles University in Prague recruited 86 couples for the research. They questioned the men and women individually and in confidence about their relationships, their attitudes towards sex, their family backgrounds and their infidelities.

Psychologist Martie Hasleton said the findings could be explained by genetics.

Good-looking fathers tended to have good-looking sons, she said.

“We would expect men and women to use their attractiveness in different ways - men to get sexual variety, and women to get the best partner possible and a good dad for their kids.” - Daily Mail
