Unit 6: Genetic Drift and Speciation

This review will guide you through an adaptive, research-backed study session. As you answer questions, we will actively assess your current understanding of the material. Questions will continue to be drawn until you have demonstrated mastery of each learning objective.

Reviews are graded based on completion. You will receive full credit for achieving 100% mastery or answering all questions.

Learning objectives for this review:

  • Define genetic drift and its role in speciation.
  • Explain how small population sizes can lead to genetic drift.
  • Discuss examples of genetic drift leading to speciation, such as in Caribbean lizards.
