Question

Based on what we know about meadow voles (i.e., they do not form pair-bonds and have multiple mating partners), which peptide hormone receptor would you expect to show decreased levels in promiscuous human males in comparison to monogamous human males? (Assume here that voles and men have similar receptor distributions.)

Answer 1

Vasopressin.

Step-by-step explanation:

Vasopressin hormone also known as anti-diuretic (ADH) hormone that regulates the tonocity of the body and maintains the fluid composition. This hormone is released from the posterior pituitary.

The vasopressin is a peptide hormone that plays an important role in the human beings. The promiscous males have multiple sexual partner and this decrease the amount of vasopressin in these males as compared with the monogamous males as vasopressin also regulates the sexual function in humans.

Thus, the answer is vasopressin.
