Solution
The correct option is B a, b and c
The A and B genes are dominant and the O gene is recessive in the ABO blood grouping system.
Codominance occurs when both alleles show dominance, as in the case of the AB blood type (IA IB) in humans.
Furthermore, the human ABO blood groups represent another deviation from Mendelian simplicity since there are more than two alleles (A, B, and O) for this particular trait.
So inheritance of blood groups in humans are represented by the following characteristics : Dominance, co-dominance and multiple allelism.
