Could Frisky Behavior Run in the Family?

Worried your daughter will follow in your frisky footsteps when she's of age? You should be! A new study reveals that promiscuity might very well be hereditary! Turns out, a dopamine receptor gene called DRD4 gives folks a predilection to detached sexual activities including infidelity and one-night stands, reports LiveScience.com.

Researchers collected DNA samples from 181 young adults and examined their relationship and sexual histories. "Individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity," Justin Garcia, a postdoctoral fellow at Binghamton University, State University of New York, said in a statement. "The motivation seems to stem from a system of pleasure and reward, which is where the release of dopamine comes in. In cases of uncommitted sex, the risks are high, the rewards substantial and the motivation variable -- all elements that ensure a dopamine 'rush.'"

Garcia said the relationships were "associative," meaning not everyone with this genotype will have one-night stands or cheat on their partners, but his findings did reveal that those with the DRD4 gene did have a higher probability of engaging in these behaviors. The same gene has also been connected to other risky behaviors, such as alcoholism, gambling addiction and even being attracted to harmless portrayals of risk (such as watching horror films).

What do you guys think? In considering the people you know, do you think it's possible that risky or slutty behavior is genetic?
