Description
In this exercise you will investigate the effects of genetic drift alone by ensuring that adaptive evolution as a result of selection cannot occur. Since natural selection requires phenotypically expressed genotypic variation, we must eliminate the source of this variation by setting the mutation rate to 0%.
Student Learning Goals
- Students will be able to explain how non-adaptive evolutionary change can occur.
- Students will be able to explain the relationship between population size, population diversity, and genetic drift.
- Students will be able to graph and explain how population size and genetic drift influence the frequency of traits or alleles over evolutionary time.
