Question

The arbitrary choice (Fisher's runaway) hypothesis requires:

(a) that the male trait is an honest indicator of the male's overall genetic quality.
(b) that the male trait that the female prefers is heritable.
(c) that all offspring of a male with the preferred trait have higher average fitness than
the offspring of males without the trait. (d) all answers are correct.

Answer 1

The arbitrary choice (Fisher's runaway) hypothesis requires that all options (a), (b), and (c) are true.

Step-by-step explanation:

The arbitrary choice (Fisher's runaway) hypothesis requires that all answers are correct. This means that all of the options (a), (b), and (c) must be true for the hypothesis to hold.

Option (a) states that the male trait is an honest indicator of the male's overall genetic quality. Option (b) states that the male trait that the female prefers is heritable. Option (c) states that all offspring of a male with the preferred trait have higher average fitness than the offspring of males without the trait. Therefore, the correct answer is (d) all answers are correct.
