Microevolution refers to:
A)any change in the frequency of alleles in the gene pool of a population
B)only changes that occur due to natural selection
C)only changes due to mutations
D)the evolution of new species

Question

Quizplus · Accepted Answer

Microevolution refers to changes in the frequency of alleles in a population over time, which can occur for various reasons such as genetic drift, gene flow, and natural selection. It does not necessarily involve the formation of new species, so option D is incorrect. Option B is incorrect because microevolution can occur due to other factors besides natural selection, such as genetic drift. Option C is incorrect because mutations are only one source of genetic variation, and not all changes in allele frequencies necessarily involve mutations.
