Codominance is a pattern of inheritance in which the alleles of the pair of a gene in a heterozygotic organism are completely expressed. Consequently, the offspring’s phenotype is the merger of the parental phenotype. Hence, the trait is neither termed as recessive nor dominant. Both the alleles in codominance would express themselves simultaneously leading to the formation of a new phenotype.
The phenomenon of codominance in human beings is exhibited by the individuals having AB blood group. The individual inherits alleles IA and IB from the parents. Both these alleles would express themselves fully and would lead to the formation of AB blood group.
