A Function-Disrupting Mutation in the Progesterone Receptor Gene Would Likely

Question

A function-disrupting mutation in the progesterone receptor gene would likely result in
A)the absence of secondary sex characteristics.
B)the absence of pituitary gonadotropin hormones.
C)the inability of the uterus to support pregnancy.
D)enlarged and hyperactive uterine endometrium.
E)the absence of mammary gland development.

Accepted Answer

The progesterone receptor is necessary for the uterus to be able to support a developing pregnancy. A disruption in this gene would lead to an inability of the uterus to respond to progesterone, which is necessary for maintaining the pregnancy. Therefore, choice C is the best answer.
