Type of Dominance Definition
Complete dominance phenotype of the heterozygote is the same as the phenotype of one of the homozygotes.
Incomplete dominance phenotype of the heterozygote is intermediate (falls within the range) between the phenotypes of the two homozygotes.
Codominance phenotype of the heterozygote includes the phenotypes of both homozygotes.
