Yes...if the mother has a B blood group (AB, BB, BO) and is or carries negative rh. factor.
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.
No, the child will inherit either the A or the B blood type antigen from the mother, plus any blood type antigen the father might provide. This would mean the child can only be A, B, or AB (should the father provide the opposite blood type antigen that the mother provides).
yes
no
no
no
No, they will have a O negative child.
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.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
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.
it is rh negative and rh positive that u dont want to mix not the a b o types it is the + or - two ++ mom n dad or two -- mom n dad not 1 positive(+) and 1 negative(-)
