Microevolution involves
A)changes to the number of individuals in a population.
B)changes in a population's gene pool.
C)a change in the ratio of males to females in a population.
D)the fixation of an allele over a long period of time.

Question

Quizplus · Accepted Answer

Microevolution refers to small-scale changes that occur within a population, and these changes are typically related to alterations in the frequency of alleles within the gene pool of that population. Therefore, option B is the correct answer. Option A is incorrect because changes in population size are not necessarily indicative of microevolutionary changes. Option C is not correct because the ratio of males and females in a population can change without necessarily indicating any specific genetic changes in that population. Option D is incorrect because the fixation of an allele refers to a specific event that can occur during microevolution, but it does not encompass all possible changes that can occur within a population.
