Virtual Lab: Mendelian Inheritance using Punnett Square Simulator

Completion requirements
  1. Access the Tool:
    Visit the Punnett Square Calculator:
    https://scienceprimer.com/punnett-square-calculator

  2. Complete the Following Tasks:

    Part A: Monohybrid Cross

    • Select 1 trait.

    • Enter the parent genotypes: Aa × Aa

    • Observe the resulting Punnett Square.

    • Record:

      • All possible genotypes and phenotypes

      • Genotypic ratio

      • Phenotypic ratio

    Part B: Dihybrid Cross

    • Select 2 traits.

    • Enter parent genotypes: AaBb × AaBb

    • Observe the 4x4 Punnett Square.

    • Record:

      • List of genotype combinations

      • Phenotypes and how they are derived

      • Ratios (genotypic and phenotypic)

  3. Answer the Following Questions:

    • What patterns do you notice in the monohybrid vs. dihybrid crosses?

    • How does this relate to Mendel’s Law of Segregation and Law of Independent Assortment?

    • How would results differ if one parent were homozygous recessive for both traits?

  4. (Optional Challenge):
    Try a Trihybrid Cross and describe the complexity of the resulting Punnett Square.


Submission Requirements:

  • A PDF or Word document containing:

    • Screenshots of each simulation (Monohybrid and Dihybrid crosses)

    • Your answers to the questions above

  • File Name Format: YourName_PunnettSquareActivity
