No, the child's blood group would be the same as one of it's parents.
Yes.
yes
Yes, it is possible for an A positive mother and a B positive father to have an O negative child. This can happen if both parents are carriers of the O negative blood type, which can be inherited from ancestors. In this case, the child would inherit one O gene from each parent, resulting in an O negative blood type.
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 possibilities include B positive, B negative, O positive, O negative.
No. They can have an O positive, an O negative, A B positive, or a B negative child.
No. The child would be either type O or B, and either rH negative or positive.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
No, they will have a O negative child.
B positive or negative or, O positive or negative.
no
Yes.
no
No, the child could only be O+ or O-.
If a person who is O- were to mate with a person who is AB+, they could not have an O+ child. They could have a child who is A-, A+, B-, or B+, but not O.
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.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
