Question

Quizplus · Accepted Answer

Studies have shown that in voles, different levels of vasopressin and oxytocin are responsible for different mating and parenting patterns. Prairie voles have high levels of these hormones, which leads to monogamous mating and extensive parental care. In contrast, mountain voles have lower levels of these hormones and do not exhibit monogamous mating or extensive parental care.
