Justin Garcia of of Binghamton University, State University of New York, has linked the dopamine receptor gene DRD4 to non-committal sex (one-night stands, etc…) and acts of infidelity. And because genes are passed down from parents to children, it’s highly likely that if you’re a total skank, your mother was too.
DRD4 is also linked to many neurological and psychiatric conditions, which helps explain why that hot girl you had a one-night stand with, turned out to be a total psycho.
Seriously, stop calling me.
