Either A- or B-.
The AB parent will pass on either the A or the B. The other parent, of course, will pass on the O, which becomes recessive against either the A or B. Since both parents are negative, the child will also be negative by default.
Any offspring of these two parents will always be type O. As far as the Rh status is concerned, it depends if the parent who is Rh positive is heterozygous or homozygous for the D allele.
Genetic or family studies need to be done to know with any certainty.
If the O positive parent is homozygous for D, then all offspring will be O Positive.
If the O positive parent is heterozygous for D, then ~50% of the offspring will be O positive and ~50% of the offspring will be O negative.
Baby's blood group will be either O positive or O negative.
The baby can only be O positive or O negative. Type O blood is double recessive, which means the parents have no A antigens or B antigens so there's no way they could pass them to the baby.

No. In order for someone to have AB blood, they must inherit the A from one parent and the B from the other. Therefore a parent with O blood could only have A, B or O children (depending on the blood type of the other parent).
absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.
I would need more information (like what blood types the child's grandparents are) to narrow it down. The child could be: - A negative - A positive - AB negative - AB positive - B negative - B positive
A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.
Yes. For the child to be O negative, he must have inherited an O from each of his parents and an Rh negative from each parent. This is possible with an O positive parent and an A positive parent. Blood type O can only be in the form OO (an O from each parent). Blood type A can be either AA (an A from each parent) or AO (an A from one parent and an O from the other) since A is dominant over O. So, if one parent is the AO variety of A, an O can be given. Thus, two Os can be given if one parent is blood type O and the other is blood type A, causing blood type O in the child. Rh positive can be either two Rh positives (a positive from each parent) or one Rh positive and one Rh negative since Rh positive is dominant over RH negative. Rh negative can only be two Rh negatives. If each Rh positive parent is the combination of one Rh positive and one Rh negative, they can each give an Rh negative to the child.
Yes, if the first parents' genotype is either BB+- or BO+-, and the second either AA+- or AO+-.

There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
No. In order for someone to have AB blood, they must inherit the A from one parent and the B from the other. Therefore a parent with O blood could only have A, B or O children (depending on the blood type of the other parent).
The blood type would be A positive.
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents. If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A. If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.
absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.
