If the parents are AO+ and BO-, they can create a O+ child: both parents contribute O and the AO+ parent contributes + (the child's genetic makeup would be OO+-). If the parents are AO+ and BB-, they could not create an O+ child as the BB- parent would contribute a B (possible combinations would be AB or BO in that case).
