A 2010 study found that people with the gene DRD4 VNTR, also known as the ‘thrill-seeking gene’, are more likely to have an inclination to cheat.

This is because the gene influences how the person’s brain processes dopamine, the ‘feel-good’ hormone, and usually seek out riskier behaviour to experience the same amount of satisfaction from dopamine as someone without the gene.

Researchers from Binghamton University in New York, Brown University in Rhode Island, and the University of Georgia, asked people with this genetic mutation about their sexual preferences and behaviours.

The researchers concluded people with the DRD4 VNTR gene were “significantly more likely to report having ever engaged in promiscuous sex (like a one-night stand)”.

But researchers also stressed that having this genetic mutation does not mean someone will cheat.

Hannah Reeves, a licensed marriage and family therapist told The Daily Mail “this is a common nature vs nurture question and surprisingly there is some evidence to suggest that it's the former”.

“Personality traits like impulsivity and an affinity for risk-taking do have genetic components. Some argue that people with these traits are more likely to cheat,” she said.
