Some May Be Genetically Predisposed to Infidelity

Maybe he swears it meant nothing to him. Maybe she promises it will never happen again. Whatever the situation, many couples will find themselves facing a situation in which one partner has been been unfaithful.  They will have to decide either to forgive the indiscretion and move on together, or to end the relationship. Obviously, for married couples ending the relationship typically means divorce, and infidelity continues to be among the most common reasons for ending a marriage. For those that decide to work out their relationship, questions inevitably remain about what caused the cheating partner to stray.

Part of the answer may lie in the human genetic code, as scientists continue to research links between genetics and human behavior. New studies are emerging on a regular basis relating the effect a specific gene or gene variant may have on the choices an individual makes. Several projects in the last few years have identified a number a genes, in fact, that may have a direct impact on a person&s self-control over inclinations toward thrill-seeking behavior, including infidelity.

One such study from Binghamton University, State University of New York, examined the impact of a variant of the dopamine receptor polymorphism, or DRD4, gene. Commonly associated with pleasure-seeking behaviors such as gambling and alcohol use, the DRD4 variation also demonstrated connection to uncommitted sexual activity, including one-night stands and infidelity. While the researchers did not claim the genetic variant necessarily caused such behavior, it was certainly more common in subjects with the variation.

A separate study out of the University of Queensland, Australia, looked at a different gene, specifically one associated with "social behavior and sexual motivation." By examining various combinations of arginine vasopressin receptor 1A, or AVPR1A, genes, the research team determined that certain variations were related to increased likelihood of infidelity in women. The genetic variant, however, led to no such observable increase in men.

Regardless of genetic predisposition, neither research team justified cheating solely on the basis of DNA. "The study doesn&t let transgressors of the hook," said Justin Garcia, lead researcher of the Binghamton study. Relationship experts are inclined to agree with him. While genetics may play a part, there are a number of other factors and considerations whenever a partner is unfaithful.
