Question

Quizplus · Accepted Answer

Administering a drug that inhibits the brain receptor for vasopressin in males can prevent pair-bonding in a population of prairie voles. Vasopressin is a hormone that plays a role in social behavior, including pair-bonding, in prairie voles. Inhibiting the receptor for this hormone in males prevents them from forming pair-bonds with females.
