Open calculatorPunnett Square Calculator is an educational biology tool for exploring a standard quantitative model.
Enter the requested values and use the displayed units or conventions. The calculator validates the numerical domain and applies offspring probability = product and sum of parental gamete probabilities.
Variables: P₁ = Parent 1 genotype; P₂ = Parent 2 genotype.
Example: Aa × Aa → AA = 25%, Aa = 50%, aa = 25%.
It is intended for biology study, classroom exercises and understanding the quantitative relationship represented by the model.
No. Biological models depend on assumptions and simplify real systems. Interpret the result within the assumptions of the selected model.
