Lesson 4: Disruptive Forces: Genetic Drift, Gene Flow, and Mutation
Duration of Days: 3
Lesson Objective
Explain how random processes (genetic drift, bottleneck, founder effect) impact the genetic diversity of a population.
Analyze the impacts of migration (gene flow) and mutation on a gene pool.
How can random, non-selective events completely alter the genetic makeup of a population?
What are the long-term evolutionary consequences of a drastic reduction in population size?
7.5-Hardy-Weinberg Equilibrium
7.6-Evidence of Evolution
Recognize that evolution is not always adaptive—sometimes it is entirely random.
