Detailed explanation-1: -The human ABO blood group system exhibits codominance. The system consists of three alleles A, B, and O. Both A and B are dominant in relation to O, and therefore blood group A can have the genotype AA or AO. Blood group B can have the genotype BB or BO.

Detailed explanation-2: -Genetic counseling 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 Genotype An example of this is in humans with Type AB blood. A person with AB blood type is a heterozygote. They inherit the allele for A blood from one parent and the allele for B blood from another parent. As a result of codominance, both expressions of type A and B blood are present.

Detailed explanation-4: -In the ABO blood type system in humans, blood type AB is an example of codominance. It implies that both dominant alleles are present and expressed together.

Detailed explanation-5: -The ABO blood group system is one of the best examples of codominance. There are different types of red blood cells such as A, B, AB and O with or without the Rh factor. The difference is in the antigen present on the red blood cell surface which determines the specific blood group in an organism.
