About This Quiz & Worksheet

This quiz and attached worksheet will help gauge your understanding of prezygotic barriers in speciation. Topics you will need to know in order to pass the quiz include beetles and plants.

Quiz & Worksheet Goals

Use these assessment tools to:

  • Identify what is meant by two different species of beetles that are unable to mate due to the shape of their exoskeleton
  • Identify what is meant by two species of plants that do not cross-pollinate because they flower at different times of the year
  • Species that can mate, but rarely with successful results
  • Female species that do not recognize male mating song of another species
  • Two related species of fish that can't make because they live in different lakes

Skills Practiced

This worksheet and quiz let you practice the following skills:

  • Reading comprehension - ensure that you draw the most important information from the related prezygotic barriers in speciation lesson
  • Critical thinking - apply relevant concepts to examine information about related species of fish
  • Interpreting information - verify that you can read information regarding beetles and interpret it correctly
  • Knowledge application - use your knowledge to answer questions about plants

Additional Learning

To learn more about prezygotic barriers in speciation, review the lesson Speciation ll: Prezygotic Barriers which covers the following objectives:

  • Define zygote
  • Define prezygotic reproductive barrier
  • Understanding spatial isolation and temporal isolation
  • Mechanical isolation, gametic isolation, behavioral isolation
