Genes may to blame for infidelity
(quote)
Some people may be genetically programmed to be unfaithful to their partner, a scientist has claimed.
Professor Tim Spector, of the Twin Research Unit at St Thomas's Hospital, London, says he has evidence of a genetic component to infidelity.
Focusing on women, he found that if one of a pair of twins had a history of infidelity, the chances her sister would also stray were about 55%.
In general it is estimated that just 23% of women are not faithful.
In addition, Professor Spector found the tendency for both twins to be either faithful, or unfaithful was strongest in identical pairs - who have identical genes.
He stressed that genes alone did not determine whether somebody was likely to be unfaithful - much was down to social factors.
