Punnett Square Calculator — science and physics formula calculators
The Punnett Square Calculator builds a genetic cross square from the parental genotypes and shows every possible combination of offspring genotypes. It is a helpful study aid for genetics students who want to visualize single-gene crosses and check dominant and recessive phenotype ratios. Enter two

About this tool
What Is Punnett Square Calculator? Punnett Square Calculator is a browser-based tool for Generate a Punnett square and calculate dominant and recessive trait ratios. This guide explains the result, the calculation or processing method, and correct usage. Calculation or Processing Method Enter two-letter genotypes such as Bb and bb. The square lists every allele combination and counts the expected proportions. Formula or method: Each offspring genotype is formed by combining one allele from each parent; phenotype ratios depend on dominant and recessive alleles.
