the baby may be A or O.
yes. mother can be ab negative.
yes, if you both are ab pos you can have a o neg baby. it depends on what the grandparents on both sides have as well as the parents and which is "dominate"
Sure. I'm not really sure about the AB and O thing, but it will be positive.
Yes, it is possible for an AB positive parent and an O positive parent to have an O positive child. The child would inherit one O allele from the O positive parent and one A or B allele from the AB positive parent, resulting in an O positive blood type.
No.
A, b, ab

No, i don't think so.

Yes! Yes indeed. Does the baby look like the mailman? No. O parents can't make AB babies.
