Punnett Square Teacher Resources

Everyone in the world is unique—just look at their genes!

If you’re getting ready to teach a genetics unit in biology, check out our teacher-selected and approved resources on Punnett squares. Start with the basics in a video that discusses how to solve Punnett squares and interpreting results. An online activity prompts users to complete Punnett squares with monohybrid crosses.

For a more applicable approach to the topic, have class members watch a video on the monohybrid crosses of hairy and hairless guinea pigs, or complete a lesson that explores the possible offspring of two cats, as well as potential genetic diseases and disorders. Spongebob Squarepants fans will love an engaging activity that uses characters from the popular cartoon in Punnett squares.

Whether your students have dominant traits or recessive traits, they’ll love learning more about the millions of possibilities held in the genetic cards. Lesson Planet has what you need to engage and teach them all about the fascinating world of genetics.
