Explanation:
The pleiotropic gene involved in sickle-cell anemia is an example of heterozygous advantage. This means that the heterozygous genotype is favourale over other two genotypes (recessive homozygous and dominant homozygous). Eventhough it has harmful effect (sickle cell disease carrier) heterozygous genotype enables resistance to infection (malaria) and that is why this genotype is still favourable by natural selection. This phenomenon is evidence of compromise between harmful ad benefit.
