Infidelity 'in the genes'

Playing away from home could be in the genes, according to new research, which suggests that one in four people are born to be unfaithful.

According to a new study published in the journal PLoS ONE, a person's gene could have an impact on their tendency to cheat on their spouse.

Scientists at Bringhampton University, US, found a gene that prompts men and women who have affairs to receive a 'chemical rush'.

The rogue gene, known as DRD4, is responsible for the circumstances in which pleasure chemical dopamine is released in the brain.

Lead researcher Justin Garcia said: "What we found was that individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity."

He explained that the motivation for cheating comes from a "system of pleasure and reward".

"In the cases of uncommitted sex, the risks are high, the rewards substantial and the motivation variable – all elements that ensure a dopamine rush," he added.

Women looking for the thrill of an extra marital lover should make sure to perfect their sexy pout, as the Daily Mail reports that men consider a woman's lips to be the most attractive part of her body.
