The human b-globin gene has two alleles, HS and HA, individuals that are homozygous for HS have sickle-cell anemia and a lower fitness. Individuals that are heterozygotes (HSHA) do not show sickle-cell symptoms and have a resistance to malaria.

Which type of selection is occurring with the b-globin gene?
A. stabilizing B. directional C. disruptive D. balanced E. negative frequency dependent
