Population genetics is the study of quizlet.
Microevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period. Population genetics is the field of biology that studies allele frequencies in populations and how they change over time. Allele frequency refers to how common an allele is in a population.
