Question

Quizplus · Accepted Answer

Sickle-cell anemia is caused by a genetic mutation that results in the production of hemoglobin molecules that are shaped like sickles instead of being round. This mutation provides some protection against malaria, as the parasite responsible for the disease does not survive well in sickle-shaped cells. Therefore, individuals who inherit one copy of the sickle cell gene are less likely to contract malaria, while those who inherit two copies of the gene may develop sickle-cell anemia.
