All of the following are examples of codominance EXCEPT C. ABO Blood Group system

Codominance:

• Codominance is the phenomenon in which two alleles when present together form their individual proteins and the phenotype is due to both the proteins.
• The coat color of horses, the fur of cattle, and A and B alleles in human blood are all examples of codominance.

Multiple Allelism:

• When more than two alleles of the same character exist in a population, it is called multiple allelism.
• Example: ABO Blood group in humans has three alleles. These are$i, i_{A} , i_{B}$.
