Yes. The father's phenotype is AO+*; the mother's is OO--.
No they can not. two positives do not make a negative
No
No. For two reasons: an "A" and an "O" can never produce "B," and positve blood types will never yield a negative one.
It would all depend on the Dominant and Recessive blood type genes in the mother and father it is near improbable to tell unless you take a blood sample to test the blood type. == A rhesus negative mother and positive father can produce either a rhesus negative or positive child. A type A and type O parental combination will only produce either type A or type O children. So an A- mother and O+ father will normally produce offspring having the possible blood groups of A+ or A- or O+ or O-. See the link for a full explanation.

the baby may be A or O.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
yes if both are heterozygotes
# yes, if father is + - for RH and mother - - (negative) or + - (positive); the father can generate sons A, B, or AB depending by mother's group.
It's called "positive" and "negative" - yes the "A" father and "B" mother can each give a gene to produce "AB"; The Rhesus gene is either positive or negative so the baby could get either.
no
yes
