Since O blood is recessive and B is dominant, this scenario would be possible
Yes, I think so. Mothes is like o.o. (O) and dad a.b. (AB), so the possibilitis for babies are a.o. (blood type A) and b.o. (blood type B).
No - this is not possible. The child must inherit one allele from each parent. This means that at least one parent must have a B allele in order for the child to have B-type blood. The only possibilities with B- X AB are B, A or AB.
If the father is type AO, the types of blood that the child can have depend on the mother. If the mother is AA, the child will be either AA or AO. If the mother is BB, the child will be either AB or BO. If the mother is OO, the child will be either AO or OO. If the mother is AB, the child will be AA, AB, AO or BO. If the mother is AO, the child will be either AA, AO or OO. If the mother is BO, the child will be either AB, AO, BO or OO. So, of all the possible outcomes, the child will be either AA, BB, OO, AB, AO or BO.
It is possible for a child to have a blood type that is different from either parent if both parents are carriers of a different blood type allele. In this case, the child could inherit the O negative blood type if both parents are carriers of the O negative allele.
Yes. Type O blood requires that you have two recessive genes, one from each parent. Each of your parents can carry one of these and have a different type of blood. In this case, there is a one in four chances of the child having type O blood.
No, this is not true. The child has to inherit two type O genes, however. Blood type is inherited as a co-dominant factor. For instance: Mom is A+, but her blood type genes are A and O. Because of the codominant nature of blood types inheritance, her blood is type A. Dad is O-. He has two type O genes. If, during fertilization, an ovum from the mother with type O gene combines with one of Dad's spermatozoa, the child will be type O. If an ovum with type A gene is fertilized, however, the resultant child will have type A blood. Same goes for mom who is A and dad who is B, so long as their genes are A/O and B/O, they can still have a type O child. If mom is A/O and dad is B/B, however, there is no chance the child will have type O. The child could have type B (B/O pairing) or AB, however.

Not possible. If the mother is A+, there are two possibilities, AA or AO, and if the father is O+, there is only one possibility, OO. therefore, the only possibilities of the child's blood type will be either A [AO] or O [OO].
This cross AO X BO, would yield that genotype. This cross, AA X BO, would not yield BO. AO X BB would not do it either. So, I assume only AO ( and, from the info given, BO ) is possible for mom.
