Yes
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.
No.there is no problem.Because both male and female are unable to produce rhesus antigen and there is no prouction of antibody inside the baby blood.
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

Not exactly. Human blood may have positive (ca. 80%) or negative (remaining 20%) Rhesus factor. It means that that a substance known as Rhesus factor is either found or not in a human blood test. Transfusion of "positive" blood to a "negative" recipient may result in very negative consequences (but not vise versa) . A problem known as Rhesus conflict may arise when a Rhesus-negative woman is pregnant with a Rhesus-positive baby.The name Rhesus factor comes from Rhesus monkey in which it was first found.
To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.
No, 15% of people are rhesus negative, meaning they don't have it.

yes that's possible because A is dominant on O so the baby could have A (but not necessarily). negative is possible. it would mean that both parents have Dd as a rhesus factor.
When they become pregnant there should not be any problems related to the rhesus blood groups - this would only be a potential problem if the mother was negative, and the father was positive.
no cause a positive and negative make a negative unless the positive has a really strong blood line
No. When the mother has a negative blood type and the father has a positive blood type, this could lead to Rhesus factor in the foetus. When both parents are positive blood group, there isn't a risk of becoming rhesus.
