Answer:
E (All blood types are possible)
Explanation:
The ABO blood group system in humans is a vivid example of co-dominance, where blood type A and B are codominant but are both dominant over blood type O.
Based on this genetic scenario, A codominant blood type AB can be produced, Blood type A can possess AA and AO, Blood type B can possess BB and BO, while Blood type O can only possess OO.
Hence, in a cross between a type A individual- AO or AA and a type B individual- BO and BB, gametes will be produced according to Mendel's law of segregation.
AO, AA (Type A) = A and O gametes.
BO, BB (Type B)= B and O gametes.
Hence, from the combination of these gametes, their offsprings can possess AB, AO, BO, OO which covers all the blood types.
Therefore, all blood types are possible
