Sickle cell anemia is an autosomal recessive genetic disorder. Because individuals affected by sickle cell anemia have defective hemoglobin proteins, their blood cannot transport oxygen properly. There appears to be a relationship between the incidence of malaria and sickle cell anemia. Individuals with sickle cell anemia and carriers of the sickle cell allele have some resistance to malaria. Malaria is caused by the parasite Plasmodium and is transmitted among humans by mosquitoes

4. If scientists are successful in reducing significantly or eliminating malaria, the best prediction
for what will happen to the allele for sickle cell anemia in the population is that it will
a. not be affected by the elimination of malaria
b. increase as its selective advantage is increased
c. be reduced as its selective advantage is decreased
d. disappear quickly as its selective advantage is increased
