About This Quiz & Worksheet

Genetic drift is an interesting phenomenon where changes in the frequency of alleles occur in a population and this quiz/worksheet combo will help you test your understanding of it. Some of the topics you'll be assessed on include the causes and the effects of genetic drift.

Quiz & Worksheet Goals

In these genetics assessments you'll be tested on:

  • Genetic drift's effects
  • The reason for Madagascar's unique population
  • Causes of genetic drift
  • Alleles and evolution
  • When genetic drift will have greater effects

Skills Practiced

This quiz and worksheet allow students to test the following abilities:

  • Reading comprehension - ensure that you draw the most important information from the related lesson on genetic drift
  • Interpreting information - verify that you can read information regarding the causes and effects of genetic drift and interpret it correctly
  • Information recall - access the knowledge you've gained regarding Madagascar and its unique population
  • Knowledge application - use your knowledge to answer questions about alleles

Additional Learning

To learn more about genetics, review the accompanying biology lesson called Genetic Drift: Definition, Examples & Types. This lesson is a video-lecture that covers the following objectives:

  • Describe genetic drift
  • List and explain the two major types of genetic drift
  • Differentiate between population bottlenecks and the founder effect
  • Define the following terms: alleles and endemic
