No it is not possible.
daughter can be O or B -ve or +ve.but not A
as person with blood group O has OO alleles n person with blood group B will be having either OB or BB
so they will have either O or B blood group child only.

From my understanding of genetics, that is not possible. Fist off, ignore the + and - portions, those are seperate from the A B or O part.
O is recessive, so for Mom to have O blood, she has to be oo. If she were Ao, her blood would by typed A. Dad could be BB or Bo, if he were AB, he would be typed AB, not just B.
So Mom can only give the baby an o gene. Dad could give a B or an o. If Dad gave a B it would make the baby Bo and s/he would be typed B, if Dad gave an o, the baby would be oo and typed O. No where in this is an A gene.

It's possible. Blood types, the same as everything else, have dominant and recessive traits. If Mom or Dad had a parent who was A, then absolutely. Usually, a child's blood type will match at least one parent's, but recessive traits sometimes sneak by. Traditionally, blood typing was thought to be very simple, even a way to confirm paternity, but DNA is a messy thing. If there are doubts about a person's parentage, DNA testing is easy and relatively inexpensive, these days. Good luck sorting out this mystery!

Rather not.
0 must consist of 00, because A or B are dominant over 0. A and B are equal.
B can consist of BB or B0 (there are always two chromosomes, 1 allel on each).
So A could be A0 or AA, but you can't get the A allel from the mother or father in the question.

No they could not have produced a daughter who is A. The daughter'd have to be a B type or possibly an O type if the parent with B type was heterozygous for the B antigen.

I looked at a chart in a doctors office a while ago and was very surprised at that blood types and produce in children. According to this calculator I found online below, the father is LIKELY excluded.

They can only have o or b type children. No A is possible. I don't think Dad is the dad that fathered the child.

I'm not sure but I thought you would be either O neg or B pos or neg. My husband is O+ and I am A+ all our kids are either O or A+.

it is possible, see is your mom is 0,0 that is not possible for her daughter to have a negative but if she is 0,A it is possible, just ask your doctor when you go to your next check-up he can explain it to you!
