Quizplus · Accepted Answer

Sexual selection is the process by which certain traits in a population become more prevalent over time due to their attractiveness to potential mates. This can lead to non-random mating patterns and an increase in the frequency of certain alleles in a population. Random evolution (A) and random mutation (D) do not necessarily involve changes that improve the odds of attracting a mate. Genetic drift (C) refers to random fluctuations in allele frequency that occur due to chance events, and is not specifically tied to mate attraction. Fitness (E) refers to an individual's ability to survive and reproduce, which is related to sexual selection but is not the specific process by which allele frequencies are altered.
