Which statement best explains the relationship between HbS allele frequency and malaria endemicity in Africa? When an area is ma
NNADVOKAT [17]
<h3><u>Answer;</u></h3>

When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04.

<h3><u>Explanation;</u></h3>
  • <em><u>HbS allele is the sickle cell hemoglobin allele that provides immunity to malaria. This is because people with the sickle cell allele have a selective advantage in areas where there is a high incidence of malaria.</u></em>
  • Therefore, natural selection will favor the population with HbS allele in a Malaria holoendemic (most individuals are infected) region. The HbS allele frequency in this population is expected to be high.
  • After malaria is cured, the frequency of the HbS allele should decrease in regions with a lot of mosquitoes because having one copy of the HbS allele will no longer be advantageous in these regions.
