Final answer:
Frequency-dependent selection is the selection process that can result in genetic polymorphism in a population.
Step-by-step explanation:
In population genetics, genetic polymorphism in a population can be the result of a selection process known as frequency-dependent selection.
Frequency-dependent selection occurs when the fitness of a phenotype depends on its frequency within a population.
This means that the advantage of a particular phenotype may change as its frequency increases or decreases in the population.
