Which statement below best describes the role of mutations in evolution by natural selection? A Mutations increase the genetic variation within a population, and each of the variants provides an advantage under different circumstances
B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.

Answers

The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.

Role of mutation in evolution:

The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.

Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual
