codominant
codominant A heterozygote that shows fully the phenotypic effects of both alleles at a gene locus. For example, humans of the AB blood group show the phenotypic effect of both IA and IB codominant genes.

codominance
codominance The condition that arises when both alleles in a heterozygous organism are dominant and are fully expressed in the phenotype. For example, the human blood group AB is the result of two alleles, A and B, both being expressed. A is not dominant to B, nor vice versa. Compare incomplete dominance.
