It is type A because A and B exhibit incomplete dominance

Answer: The correct answer is-

b. It is type AB because A and B are codominant.

In ABO blood typing, A and B are codominant alleles whereas allele O is recessive.

This means that an individual who inherits A and B alleles from his parents, would exhibit AB blood group.

This is because, being codominant, both A and B alleles will be expressed completely, resulting in AB blood group.
