Co-dominance with example

  1. Codominance is an effect of lacking of dominance, where there is no relationship between dominant and recessive.
  2. In this kind of situation the alleles are observed as the same degree of phenotype, which is known as codominant.
  3. Therefore, the phenotypic effect of each allele is observed as heterozygous.
  4. The example of codominant allele is M-N blood group in human.
  5. In co-dominance the ratio of genotype and phenotype remains same.
