Dihybrid Cross Calculator — science and physics formula calculators
The Dihybrid Cross Calculator builds the 16-cell F2 grid for a two-trait cross from the mother and father genotypes (for example AaBb). It lists the maternal and paternal gametes, the F2 offspring cells, and the phenotype distribution across the four phenotype classes. Use it in genetics classes to

What Is Dihybrid Cross Calculator? Dihybrid Cross Calculator is a browser-based tool for Predict offspring ratios from a two-gene cross. This guide explains the result, the calculation or processing method, and correct usage. Calculation or Processing Method Enter the parental genotypes for two traits; the tool computes phenotypic and genotypic ratios from the sixteen-cell grid. Formula or method: For two independent traits, crossing two dihybrids AaBb × AaBb gives a 9:3:3:1 phenotypic ratio because each allele pair segregates independently.
