Best Answer

Yes.

If the mother has one A gene and one O gene, and the father has one A gene and one O gene, some children may inherit the O gene from both parents, and therefore be type O.

If the father is heterozygous (one gene is Rh+) Rh positive, the chances are 50% that the child will be positive. If the father has both genes Rh+, the child will not be Rh negative.
