Explanation:
Detailed explanation-1: -For parents who each carry the sickle cell trait, the chance that their child will also have the trait–and be immune to malaria–is 50 percent. There is a 25 percent chance that the child will have neither sickle cell anemia nor the trait which enables immunity to malaria.
