A test to verify the hypothesis that presence of sickle-cell anemia allele protects the individual from malaria. Introduction: Sickle-cell anemia is an autosomal recessive disorder, which alters the shape of red blood cells (RBCs) to sickle-shaped and reduces the oxygen- carrying capacity of hemoglobin. The shape of RBCs is also altered in individuals who have only one copy of the defective allele. It has been hypothesized that individuals with a sickle-cell allele are protected from malaria.
