When using this activity, please give credit to my site.

This activity is to help introduce genetics and punnett squares using the toys Mr. and Mrs. Potato Head.

Potato Genetics

Background:

In the species Potato headius, gender, eye color, eyesight, and mouth type are genetic, meaning they inherit those qualities from their parents.

Materials per group:


  • Potato head body
  • Pair of ears
  • Pair of arms
  • Pair of shoes/feet
  • Penny
  • Nose




As a group, flip the coin to see the traits of your potato head. Tails= the dominant trait and heads= the recessive trait.   In the case of gender, tails=X and heads=Y.
