Biology: Punnett Pea Predictor

by Texas Instruments - Simulation Lesson


  • Students will use a Punnett square simulation to predict phenotypic and genotypic ratios of F1 generation.
  • Students will predict parental genotypes.
  • Students will explain the relationship between Punnett squares and probability.


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

About the Lesson

This lesson allows students to explore patterns of genetic inheritance through a simulation.
As a result, students will:

  • Manipulate Punnett squares to model the inheritance of height in pea plants.
  • Predict genotypic and phenotypic ratios of offspring.
