So to have a type O blood type you also need to have a H_ genotype along with the usual IOIO. It is worth memorizing how the blood types interact by the way. So the probability that the offspring will have a H_ genotype is 75% and the probability that it has type O blood is 25%. Multiply these two together and the ratio is 3/16 or about 19%. ................
