1Sickle-cell disease is caused by a mutation that produces an abnormal protein. The gene for sickle-cell disease causes a person'sred blood cells to be shaped like a sickle instead of being round and flat. Sickle-shaped red blood cells do not carry oxygen verywell, which causes health problems and lowers survival rate. However, in areas where malaria is common, people that have thesickle-cell gene are protected from malaria. The malaria parasite relies on normal red blood cells to grow, and cannot easilycomplete its life cycle in sickle-shaped cells.What does the given information demonstrate?A.
