How can a child's blood type be A positive if mom is O positive and dad is AB negative?
because the dad blood was stronger and one positive and one negative make a positive

Can an O negative mother with RH negative and an O positive father make an A positive baby?
YES. Blood type is determined by two alleles. An "A" individual can be homozygous "AA" or heterozygous "AO" and still be considered type A. The same is true of a "B" individual. If the father is "AO" and the mother is "BO" then statistically, they have a 25% chance of having a child that is "OO" or type O.
Is it true that to have a child with O blood type both parents have to be O type?
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.
