This is great as homework or reinforcement activity. Students should have prior knowledge of these concepts before completing this worksheet.

This Worksheet Has Several Parts:

  • Complete 2 Punnett squares for an example of complete dominance and answer questions related to the results.
  • Complete a Punnett square for an example of codominance and analyze the results.
  • Complete a Punnett square for an example of incomplete dominance and answer analysis questions.
  • Students make their own Punnett square to show incomplete dominance.
  • Answer follow-up questions.

Vocabulary in This Lesson:

  • Complete dominance
  • Incomplete dominance
  • Codominance
  • Alleles

NGSSHS-LS3-1
Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.
NGSSMS-LS3-2
Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. Emphasis is on using models such as Punnett squares, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation.
