Question

question 31 1 pts how do natural selection and sexual selection differ? natural selection increases the frequency of alleles that contribute to survival, but sexual selection may increase the frequency of alleles that are not beneficial to survival. natural selection is more random than sexual selection. natural selection contributes to genetic drift, but sexual selection contributes to gene flow. natural selection increases the fitness of an allele, but sexual selection increases the dimorphism of an allele.

Explanation:

Natural selection favors traits that enhance survival and reproduction in an environment, increasing the frequency of alleles that contribute to survival. Sexual selection, on the other hand, is based on traits that increase mating success, which may not always be beneficial for survival (e.g., elaborate peacock tails that can be a predator - attraction risk).

Answer:

Natural selection increases the frequency of alleles that contribute to survival, but sexual selection may increase the frequency of alleles that are not beneficial to survival.
