Step 1/2

Which of the following statements best describes sexual selection?

The phrase "Sexual selection occurs when there is a difference in mating success among individuals of the same sex with different phenotypes" sums up sexual selection the best. Competition for mates drives the process of sexual selection, which leads to the evolution of features that improve a person's chance of successfully mating. These characteristics might be physical or behavioral, and both sexes may display them. Consequently, sexual selection does not exclusively affect males or act on features associated with mate-finding or adornment in males.

The alternative choices are erroneous because they offer a constrained or misinformed understanding of sexual selection:

Sexual selection can affect a variety of traits that affect mating success, including physical traits like body size, coloration, and weaponry as well as behavioral traits like courtship displays and vocalizations. The claim that sexual selection only affects traits related to finding a mate is untrue.

"Sexual selection" is the practice of selecting males for ornamental qualities that aid in mate attraction. Sexual selection can affect a variety of other features in addition to ornamentation, therefore it is not the only sort of trait that can be selected for.

"Sexual selection only affects males" is untrue because it affects both males and females and in some species, it may affect one sex more strongly than the other.

Step 2/2

SUMMARY OF THE ANSWER:

Explanation:

The easiest way to define sexual selection is to say that it is a particular kind of natural selection that is motivated by competition for mates. The evolution of features that improve a person's chances of mating and having children is the result of sexual selection. These characteristics might be behavioral, like courtship rituals or mating sounds, or physical, such size or colouring. Both males and females are subject to sexual selection, which can lead to the development of secondary sexual traits like antlers or vivid plumage. Overall, sexual selection has a significant impact on the diversification of life on Earth and the evolution of reproductive strategies.
