In genetics the terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are being expressed separately to produce the different traits in the individual. In perfect dominance, only the one allele of the genotype is also present in the phenotype. In codominant cases, both the alleles of the genotype are present in the phenotype. In the case of the imperfect dominance, the phenotype shows the mixture of genotypic alleles. In the genetics terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are expressed and separately to produce the different traits in the individual.
