Humans may have rh+ blood or rh- blood. A person who is rh+ (r) has a certain type of protein on the red blood cells. A person who is rh- (r) does not have this particular protein. In humans, rh+ dominates rh-. Normal insulin (i) production dominates abnormal insulin production (i) (diabetes). If both parents are heterozygous for both rh+ and normal insulin production, what phenotypes would they produce in their offspring? what are the probabilities of producing each phenotype?
