Virtual Lab: Mendelian Inheritance using Punnett Square Simulator

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:

  • Screenshots of each simulation (Monohybrid and Dihybrid crosses)

  • Your answers to the questions above
