The expected phenotypic ratio in the F2 generation of a dihybrid cross following Mendelian inheritance is 9:3:3:1. This means that out of four offspring, three will show one phenotype and one will show a different phenotype. This ratio results from the independent assortment of two different traits, each controlled by a different gene.
