No - blood group O is recessive, two O parents can only produce an O child. A Rh+ mother and Rh- father can produce either a Rh+ or Rh- child - Rh+ is the dominant factor.

Yes.
Yes. The father's phenotype is AO+*; the mother's is OO--.

Yes.
Yes
No they can not. two positives do not make a negative
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
