Genetic variation within a population may be maintained by
A) frequency-dependent selection.
B) the accumulation of neutral alleles.
C) sexual recombination.
D) heterozygote advantage.
E) All of the above

Question

Quizplus · Accepted Answer

All of the choices listed can contribute to the maintenance of genetic variation within a population. Frequency-dependent selection can favor rare alleles and maintain polymorphism. Neutral alleles can accumulate over time and contribute to diversity. Sexual recombination can shuffle alleles and create new combinations of traits. Heterozygote advantage can lead to the maintenance of multiple alleles, as individuals heterozygous at a particular locus have higher fitness than either homozygote. Therefore, all of the listed choices contribute to the maintenance of genetic variation within a population.
