Detailed explanation-1: -Codominance, as it relates to genetics, refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.

Detailed explanation-2: -In codominance a heterozygous individual expresses both simultaneously without any blending. An example of codominance is the roan cow which has both red hairs and white hairs. In incomplete dominance a heterozygous individual blends the two traits.

Detailed explanation-3: -Codominance is a heterozygous condition in which both alleles at a gene locus are fully expressed in the phenotype. Alleles which show an independent effect are called as Codominant alleles. In codominance, neither phenotype is completely dominant. The best example of codominance is ABO blood group.

Detailed explanation-4: -Codominance and Incomplete dominance are two types of genetic inheritance. Codominance essentially means that no allele can block or mask the expression of the other allele. On the other hand, incomplete dominance is a condition in which a dominant allele does not completely mask the effects of a recessive allele.

Detailed explanation-5: -Examples of codominance in animals include speckled chickens, which have alleles for both black and white feathers, and roan cattle, which express alleles for both red hair and white hair.
