Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
A positive, O positive, A negative, or O negative; all are possible
Yes, it is possible for a positive antinuclear antibody (ANA) test to change to negative. This could happen if the underlying condition that was causing the positive result resolves or goes into remission. However, it is important to consult with a healthcare provider for proper evaluation and interpretation of test results.

No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.
Yes. It is possible.
Yes, it is possible for a child to have a negative blood type if both parents are carriers of the Rh negative gene, even if one parent is O positive and the other is A positive. Blood type inheritance is determined by a combination of both parents' blood types and Rh factors.
