Detailed explanation-1: -Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote.

Detailed explanation-2: -The ABO blood type is inherited in an autosomal codominant fashion. The A and B alleles are codominant, and the O allele is recessive.

Detailed explanation-3: -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-4: -If alleles for a trait are codominant, they will both be equally and fully expressed. This is a bit different than incomplete dominance, in which the traits are blended. A common example given to describe codominant traits is the ABO blood typing system. There are three possible alleles for ABO blood type: A, B, and O.
