Abstract
Abstract Heterozygous advantage, also called overdominance, refers to the fitness superiority of heterozygotes over homozygotes. Heterozygote advantage, frequency‐dependent selection and some modes of selection in fluctuating environments are all forms of balancing selection, which actively maintains genetic variation.
