What is the connection between sickle-cell anemia and malaria?

Question

Quizplus · Accepted Answer

Heterozygotes for sickle-cell anemia have some resistance to malaria. The sickle-cell gene is found in areas where malaria is prevalent, suggesting that it offers some protection against the disease. This is because the parasite that causes malaria cannot survive as well in the red blood cells of those who have the sickle-cell trait. As a result, individuals who carry one copy of the sickle-cell gene are less likely to get sick from malaria.
