Question

Quizplus · Accepted Answer

While mutation introduces new genetic variation, it is often a relatively slow process and alone does not typically cause significant changes in allele frequencies within a population. Other evolutionary mechanisms, such as natural selection, genetic drift, and gene flow, often have more significant impacts on the genetic makeup of populations.
