WebSickle cell anemia is the best-known example of heterozygote advantage and balanced polymorphism in humans. As discussed in Chapter 12 and again in Figure 18.1 , the … WebThe balanced polymorphism is the polymorphism provided by the selection against both homozygotes in favor of heterozygotes. The recessive genotype is eliminated more than the dominant one. The differences in the elimination rate of those genotypes maintain the stable being of both alleles in the population with a specific rate for each.
WebPolymorphisms. A polymorphism is a genetic variant that appears in at least 1% of a population.
