If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene?
We can use the Hardy-Weinberg Equation, p2 + 2pq + q2 = 1,
to calculate genotype frequencies from known phenotype ratios. The frequency of homozygous ...
