Quizplus · Accepted Answer

The graduate student's statement suggests that there are two distinct mating systems between the two squirrel species, similar to the monogamous and promiscuous mating systems in prairie and montane voles. Option B correctly identifies the hormonal differences between these two mating systems, where the monogamous species has higher levels of vasopressin and oxytocin receptors promoting pair bonding, while the promiscuous species has lower levels of these receptors not promoting pair bonding. Options A, C, and D mention either the wrong neurotransmitters or the wrong mating system, making them incorrect.
