Scientists Identify Gene That May Cause Promiscuity

December 7, 2010

(ChattahBox Science News)—Researchers have isolated a gene that they say makes people more promiscuous and more likely to cheat on their partners, ABC News reports. People with a variant of the DRD4 gene involving longer alleles (part of the DNA sequence) appear to have more of a proclivity for “thrill seeking” activities such as skydiving, gambling, or having sex.

Investigators at Binghamton University with the State University of New York discovered the gene variant following a study of 181 college students and determined that the patients with longer alleles were more likely to seek thrills. The researchers also noted that the gene is inheritable, meaning that it runs in families, ABC News notes.

The gene isn’t solely responsible for a person’s proclivity to treat, experts tell ABC News. It may make them more vulnerable to affairs, but they are still armed with personal choice and impulse control.
