No. They can have an O positive, an O negative, A B positive, or a B negative child.
The father would be fat.
Yes, if both the mother and the father are carriers of the recessive Rh negative trait, they can produce a child with O negative blood type. The child would inherit one Rh negative allele from each parent, resulting in a negative blood type.
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
