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.
