d) Cheetahs experience a population bottleneck.

Answer 1

The correct answer is option b) "Peahens choose to mate with peacocks that have the brightest tails".

Step-by-step explanation:

According to evolutionary theory, sexual selection is a type of natural selection at which members of one sex chose their mates based on a trait that is advantageous for the species. This functions as a competition among members of the selected trait. Peahens choose to mate with peacocks that have the brightest tails is an example of sexual selection. Brightest tails is an evolutionary advantage for peacocks, therefore peahens selecting them functions as a sexual selection.
