Main Difference – Codominance vs Incomplete Dominance

According to Mendel, the phenotype of the offspring always resembles the parents. On that account, the phenotype of the offspring is determined by the number of dominant and recessive alleles for a particular trait. But, the interactions between different alleles determining a particular trait complicate the Mendelian inheritance. The inheritance of alleles, which are not completely dominant or recessive, gives rise to the two concepts called codominance and incomplete dominance. The main difference between codominance and incomplete dominance is that in codominance, a cross between individuals with two different phenotypes produces an offspring with a third phenotype, showing both parental phenotypes together whereas, in incomplete dominance, a cross between individuals with two different phenotypes produces an offspring with a third phenotype, which is a blend of the two parental phenotypes.

In both codominance and incomplete dominance, both alleles for a trait are dominant. In codominance a heterozygous individual expresses both simultaneously without any blending. An example of codominance is the roan cow which has both red hairs and white hairs. In incomplete dominance a heterozygous individual blends the two traits. An example of incomplete dominance is the pink snapdragon, which receives a red allele and white allele.
