Answer

Answer:

The frequency will increase.

Explanation:

Step1: Understand HbS gene

The HbS gene is related to sickle - cell trait.

Step2: Malaria resistance

Heterozygotes (with one normal and one HbS allele) have some resistance to malaria.

Step3: Allele frequency change

During a malaria outbreak, individuals with the HbS allele have a survival advantage, so the frequency of the recessive HbS allele will increase in the population due to natural selection.
