Blood types are based on enzymes that place specific sugars onto the surface of red blood cells. As was shown, the sugars added by the IA and IB genes, which give blood types A and B, are attached to a 'basal antigen' group of sugars which is the chain of purple sugars on the cell on the left. Although it is very rare, there are people who have a recessive mutation that causes them to not make this basal sugar group, as shown on the cell on the right. They can never deposit the extra sugars that display blood types A and/or B. So my question is: can a person who has this recessive mutation still have children who display they are blood type A and/or blood type B? Explain your answer.
