[Campbell Biology P.548] Which of the following statements about sexual selection and sexual... | Practice Question
Which of the following statements about sexual selection and sexual dimorphism, as described in the text and Figure 23.15, is INCORRECT?
A: Sexual dimorphism refers to differences in secondary sexual characteristics between males and females of the same species.
B: Intrasexual selection involves competition among individuals of the same sex for mates of the opposite sex.
C: A peacock's bright plumage, despite potentially making it more visible to predators, is an example of a trait favored by intrasexual selection because it helps the male gain a mate.
D: Intersexual selection, also known as mate choice, typically involves females being choosy in selecting mates based on appearance or behavior.
Explanation
The text defines intrasexual selection as competition within the same sex and intersexual selection mate choice as individuals of one sex usually females being choosy based on the other sex's appearance or behavior. The example of bright plumage in peacocks is explicitly linked to female choice, which falls under intersexual selection, not intrasexual selection.
