Explanation / Answer

In some circumstances, natural selection will maintain rather than remove variation.

When the fitness of a phenotype depends on its frequency within the population, it is called frequency - dependent selection.

Rare phenotypes are favored by selection in negative frequency dependent selection.

Common phenotypes are favored in positive frequency dependent selection.

Sometimes, oscillating selection occurs where one phenotype is favored atone time and another phenotype is favored at another time.

Heterozygote-advantage selection will favor individuals with copies of both alleles rather than two copies of the same allele.
