Meet the Grays--an average family. Mira cooks, cleans, wears dresses, is sexually frustrated and her spouse is a workaholic veterinarian. Their son, almost 18, has a new girlfriend that he wants to lose his virginity with, is always hungry, and is constantly pulling on his penis. The only way in which this family is not conventional is that the parents are both women. What happens when their son wants to know who his dad is? The Gene Pool explores the family's relationships and how they are dealing with their mid-life crises, their son's resolution to lose his virginity, and… oh yeah, his question, "Moms, who is my Dad?"
