Calculate genotype and phenotype ratios instantly with our free Punnett square calculator. Solve monohybrid and dihybrid crosses for genetics homework, breeding programs, and biology education.
Predict genotype and phenotype ratios for genetic crosses. Calculate monohybrid and dihybrid inheritance patterns instantly.
Enter parent genotypes using standard notation (e.g., Aa for monohybrid, AaBb for dihybrid crosses).
Examples:
A Punnett square is a diagram that helps predict the probability of different genotypes in offspring.
Capital letters represent dominant alleles, while lowercase letters represent recessive alleles.
The phenotype is the physical expression of the genotype. A dominant allele will mask a recessive allele in the phenotype.
