Sickle cell anemia, a recessive deadly blood cell disease, is much more common in tropical climates because carriers (heterozygotes) are resistant to a deadly parasitic disease carried by mosquitoes (malaria). Given this information which of the following scenarios is a possibility?
A. The widespread availability of any drug that protects a population from malaria will have the side effect of reducing deaths from sickle cell anemia over many generations.
B. Having malaria will begin to give immunity to sickle cell anemia as well.
C. Populations in areas where there are fewer mosquitoes will have more and more sickle cell anemia as time goes on.
D. Genetie drift will always be so strong in these populations that none of this selection will be impactful, even for extremely large populations.
E. Over many generations the mosquitses must develop sickle cell anemia too.
