In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the β hemoglobin alleles in the human gene pool.
-Although selection is clearly present, if the ideal equilibrium of alleles existed, what should be the proportion of heterozygous individuals in populations that live here?

The Hardy-Weinberg principle can be used to calculate the expected proportion of heterozygous individuals. If the sickle-cell allele frequency is 0.20, then the normal allele frequency is 0.80. The proportion of heterozygous individuals is 2pq, where p is the frequency of the normal allele and q is the frequency of the sickle-cell allele. Thus, 2(0.80)(0.20) = 0.32.
