What Results When Traits are Acted on by Sexual Selection

Question

What results when traits are acted on by sexual selection?
A) The traits increase fertility.
B) The traits occur mostly in females.
C) The traits sometimes appear to have no relation to fitness.
D) The traits occur in plants but not in animals.

Accepted Answer

Sexual selection can sometimes favor traits that appear to have no direct relationship with survival or fitness, such as elaborate courtship displays or brightly colored feathers. These traits are often chosen by potential mates and can contribute to reproductive success, even if they do not directly affect survival. The other choices are not accurate as sexual selection does not always result in increased fertility and can occur in both males and females, not just females. Additionally, sexual selection occurs in both plants and animals.
