Enter two parent genotypes to generate a Punnett square and offspring probabilities.
Each parent contributes one allele to the offspring. The calculator creates all possible allele combinations:
Offspring Genotype = Allele from Parent 1 + Allele from Parent 2
The Punnett square displays all four combinations and calculates genotype probabilities.
Parent 1 = Aa Parent 2 = Aa Possible Output: AA = 25% Aa = 50% aa = 25%
