In recent years, the country of Zambia in Africa has had increasing cases of malaria. If 8 % of the 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, under the Hardy-Weinberg assumption

Question
In recent years, the country of Zambia in Africa has had increasing cases of malaria. If 8 % of the 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, under the Hardy-Weinberg assumption?
Expert Solution
Introduction:
Hardy -Weinberg (H-W) provided a null hypothesis for the population not evolving. If all H-W assumptions were met, the allele frequencies and genotype frequencies can be linked by H-W equations. The following assumptions should be true for that population:
- The population should be large.
- There should be no mutations happening
- There should be no immigration or emigration, hence no gene flow.
- The mating between individuals should be random without sexual preferences
- Natural selection should be absent.
