<p>Blame your bad behaviour on the "cheating gene'' in your genetic make-up, according to a study.The study by New York-based Binghamton University Justin Garcia has linked promiscuous behaviour to the "cheating gene'' DRD4.<br /><br />Based on DNA scraped from the cheeks of 181 sexually active young people, Garcia has found a link between a variant of DRD4, a gene that affects dopamine receptors, and infidelity, one-night-stands, drinking and thrill-seeking, according to a Canadian daily.The DRD4 has also been dubbed the "slut gene.''<br /><br />"We all have the so-called promiscuity or 'cheating gene,' '' Garcia told the Vancouver Sun in an interview."The DRD4 gene, which affects the dopamine receptors in the brain, is important for pleasure and reward.<br /><br />"It (DRD4) goes off when you jump out of an airplane, engage in sexual behaviour, drink alcohol and gamble,'' the researcher said.If you carry a certain variant of the DRD4 gene, you might be pre-disposed to repetitive, intense sexual sensation-seeking: one-night-stands and infidelity, he told the paper.<br /><br />"Whereas some people might jump out of a plane and say, wow, that was great, another person might skydive, land and say hey, I want to go up again!''<br /><br />Garcia told the paper that there is a strong correlation between pleasure and reward for dopamine addicts and risk-takers: uncommitted sex and one-night-stands fit the high-risk, high-reward structure that results in the pleasurably, addictive dopamine rush.<br /><br />But he added, "We can have these genes that predispose us to certain kinds of behaviour</p>
