Question

Quizplus · Accepted Answer

Balancing selection is occurring in areas where malaria is present. This is because the sickle-cell allele, while harmful in homozygotes, provides resistance to malaria when heterozygous with the normal hemoglobin allele. Balancing selection maintains both alleles in the population, despite the harm caused by the sickle-cell allele in homozygotes.
