To observe how selective forces can change allele frequencies in a population and cause evolution to occur.
Allele frequency refers to how often an allele occurs in a population.
Allele frequencies can change in a population over time, depending on the selective forces shaping that population. Predation, food availability, and disease are all examples of selective forces. In this activity, red and white beans are used to represent two alleles of b globin. The Gene Pool exists in a region of Africa that is infested with malaria. You are simulating the effects of a high frequency of malaria on the allele frequencies of a population.
