Question

Quizplus · Accepted Answer

Individuals with an allele for sickle-cell anemia are more resistant to malaria. This is because the sickle cell trait alters the shape of red blood cells, making it difficult for the malaria parasite to survive within the cells. As a result, individuals with the sickle cell trait are less likely to contract malaria, which is a common disease in areas where the parasite is endemic.
