Question

Quizplus · Accepted Answer

Being a carrier for sickle cell anemia results in a balanced polymorphism. This is because carriers have a selective advantage in areas where malaria is common, as they are less likely to contract the disease. Therefore, the sickle cell trait is maintained at a frequency higher than what would be expected under genetic drift or disruptive selection. The Red Queen effect and sexual selection are not applicable in this scenario.
