Answer:
Yes, it is possible to produce a blood type AB from blood type A and B.
Explanation:
If we were to do a hybrid cross and the mother's blood type was A, then her genotypes would be AA and AO. Additionally, if the father had type B blood, his genotypes would be BB and BO. From this, we can tell that the child's genotypes would have to be A, AB, B, O. Since AB is one of the choices, yes, it is possible to produce a blood type AB from blood type A and B.
The only times where you won't be able to produce a child with type AB is if both of the parents have type B blood and type O blood. Or if one parent has type B blood and the another has type O blood. Or if one parent has type AB and the other one has O blood. Or if both parents have type A blood.
