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.
Yes, the baby could be positive. If the baby is positive the mother needs to get on immuno-suppressant drugs or she will have an immune reaction and her body will try to kill the "foreign object" aka the fetus. Best of luck.
I am no professional so I may be wrong, but normally the child takes after their father so I think the child will be an O negative.
The baby's blood type would depend on the specific genotype of both parents. With a mother who is O-positive and a father who is Rh-negative, the baby could potentially have blood types A-negative, B-negative, AB-negative, or O-negative.
No, the baby cannot be A-. A and B genotypes are codominant and O is recessive. Since the father is B and not AB, his genotype must be either BB or BO. The mother is OO. So there is no way for them to have an AO or AA baby. The baby can be Rhesus negative however, because the father may be heterozygous for the Rhesus factor.
Yes, the firstborn baby can be Rh negative if both parents carry the Rh-negative gene. The Rh factor is inherited from the parents, and if the mother is Rh negative and the father is also Rh negative, their child will be Rh negative. However, if the mother is Rh positive and the father is Rh negative, the child can either be Rh positive or Rh negative depending on the specific alleles inherited.

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.
the baby may be A or O.
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
B negative
no
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
yes its possible
