Incomplete dominance is a type of inheritance in which the heterozygous genotype has a phenotype that is intermediate between the phenotypes of the homozygous genotypes. In the case of sickle-cell trait, the heterozygous genotype (one recessive gene for the sickle-cell trait along with one normal dominant gene) results in a phenotype that is resistant to malaria and does not have sickle-cell anemia.
