The high frequency of hemoglobin alleles linked to the devastating disease, sickle- cell anemia, in areas with high incidence of malaria suggests that: O Individuals that are heterozygote of sickle-cell anemia were retained in the population due to their fitness advantage against malaria. O The retaining of individuals with the autosomal recessive disease is an example of purifying selection O The retaining of individuals with the autosomal recessive disease is an example of directional selection O natural selection is not true because individuals with the devastating disease is retained in the population.
