Life Science: Punnett Squares

by Texas Instruments - Simulation Lesson


  • Students will discover how traits can be passed on from parents to offspring.
  • Students will predict the traits parents will pass on to their offspring and specify how parents need to combine in order to generate a specific trait in their offspring.


  • allele
  • genotype
  • phenotype
  • homozygous
  • dominant
  • recessive
  • heterozygous

About the Lesson

In this lesson, students will gather data on traits expressed in offspring and explore how allele combinations in parents produce phenotypic ratios in their offsprings.

As a result, student will:

  • Complete Punnett squares.
  • Collect data on phenotypic ratios.
  • Use collected data to spot a pattern in how dominant and recessive alleles are expressed.
