Do you have a lot of one-night stands? Affairs? Well, I bet your mom does too. No, really! I bet she does, because scientists say they've found a gene that's linked to promiscuity and uncommitted sex.

According to research by Justin Garcia, of Binghamton University, State University of New York, the dopamine receptor gene DRD4 is connected to promiscuous behavior, and people with the gene "were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity." So, yes, now you can officially blame that one time with the woman from the juice bar on your genes, and not on the fact that you are a cheating slut. (This is called scientific progress!)

DRD4, of course, is the "thrill-seeking" gene, which means that it's also the "loving horror movies" gene, and, less charmingly, the "gambling addiction" gene. And, of course, the "politically liberal" gene. So, really, DRD4 isn't just the slutty gene: It's the awesome gene.
