Question

Quizplus · Accepted Answer

Genetic variation is the most important concept in population genetics as it forms the basis of evolution through natural selection, genetic drift, and gene flow. Population size and rates of mutation are important factors that influence genetic variation, but they are not the fundamental concept. Phenotypic variation is an important outcome of genetic variation, but it is not the central concept in population genetics.
