Detailed explanation-1: -In some chickens, the gene for feather colour is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.
Detailed explanation-2: -For Example: In chickens, the allele for black feathers is co-dominant with the allele for white feathers. These chickens will have BOTH black and white feathers.
Detailed explanation-3: -In chickens, black and white feathers are codominant. Heterozygous chickens have a checkered pattern.
Detailed explanation-4: -Since both the A and the B alleles are visible in the blood, the trait is codominant. AB blood type is codominant because the red blood cells have the products of both the A and the B alleles of the ABO gene.
