No. For two reasons: an "A" and an "O" can never produce "B," and positve blood types will never yield a negative one.
No. The child would be either type O or B, and either rH negative or positive.
B positive or negative or, O positive or negative.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
Yes to both.
No, O positive and B positive parents cannot have a B negative child. A child with B negative blood type must inherit a B allele from both parents, which is not possible in this scenario as the O positive parent does not carry the B allele.
No. They can have an O positive, an O negative, A B positive, or a B negative child.
Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.
The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.
The child will be either B or O (not A or AB), but whether positive or negative is impossible to say.
Yes. The child will be either A positive or B positive or even AB positive. If the grandparents have a negative (A negative, B negative), there is a slight chance that the child will have a negative. A type O is out of the question. The fact that there are two positive parents means that there is no risk to the mother of Rh negative disorders.
Yes.
The child may have either O or B blood type, assuming that the mother has a recessive allele for O blood type. A child of parents with both positive and negative Rh factor may have either. So, the child could have O positive, O negative, B positive, or B negative blood types.
