Crews and colleagues (1984, 1987) examined patterns of reproduction with regard to (1) gamete production, (2) secretion of sex steroids, and (3) timing of mating behavior in a wide variety of vertebrates and found that three general patterns of reproduction emerged. In the Norway rat, for example, it has been found that gonadal growth and an increase in circulating levels of sex steroids activate mating behavior. This pattern would be an example of a(n)
A) associated reproductive pattern.
B) dissociated reproductive pattern.
C) interventional reproductive pattern.
D) opportunistic reproductive pattern.

Question

Quizplus · Accepted Answer

This pattern is an example of an associated reproductive pattern because it describes a scenario where gonadal growth and an increase in circulating levels of sex steroids directly activate mating behavior, indicating that these physiological changes are closely associated with the timing of reproductive behavior.
