The difference between directional selection, over dominance, and under dominance. Introduction: Natural selection changes the genetic makeup of a population by favoring the alleles that contribute to reproductive success and selecting against those that do not. Directional selection is the mode of natural selection. Both under-dominance and over- dominance are used in genetics. In this, selection is based on homozygote or heterozygote condition.
