4. Now we know that heterozygous individuals have an advantage in malaria- prone areas. You observe that in a village in sub-Saharan Africa, the frequency of the sickle cell allele (q) is 0.17 (this number is based on actual data from Grosse et al., 2011). Assume that there are 1,000 people in this village. Based on the value of q above, calculate the observed proportion of individuals with the homozygous recessive (aa), heterozygous (2pq), and homozygous dominant (AA) genotypes. a. aa (q)-.0289 b. Aa (2pq) -- c. AA (p²) - 5. Using your answer from #4 above, calculate the observed # of individuals with each genotype: a. aa (q²) -- b. Aa (2pq) -- c. AA (p²)-
