Sickle-cell disease is an inherited blood disorder in which abnormalities in the red blood cells’ oxygen-carrying hemoglobin protein cause the cells to assume distorted, sickle-like shapes. The abnormal cells can clog blood vessels, depriving tissue of blood and oxygen and resulting in painful “crises.” The genetic disease is found predominantly in the black community, especially among those of W African descent. Scientists believe the mutation may help protect against what infectious disease? Discuss
