Quizplus · Accepted Answer

The high percentage of individuals in West Africa who are heterozygous for the sickle cell trait is an example of natural selection. This is because individuals with the sickle cell trait are more resistant to malaria, which is endemic in the region. As a result, they have a higher chance of survival and reproduction, passing on the sickle cell gene to their offspring. This leads to an increase in the frequency of the sickle cell trait in the population over time.
