Research: Some Women May Carry an ‘Infidelity Gene’

It has often been the case that cheating partners who get caught have a long list of excuses to explain away their liaisons.

But now scientists have discovered an ‘infidelity gene’ that could mean cheating women will be able to simply say their genes made them do it.

Females who carry a specific variant of a gene which affects social behaviour and sexual motivation have a greater propensity to take part in ‘extra pair mating’, researchers from the University of Queensland in Australia found.

Variants of combinations of the AVPR1A gene have been found to be associated with promiscuity and ruthlessness in animals, the Sunday Times reported.

Each person carries two AVPR1A genes – one inherited from each parent – so there are a number of potential combinations.
