In considering the cross yyrr x yyrr, the phenotype ratios of the f2 generation will be

In considering the cross YyRr x YyRr, the phenotype ratios of the F2 generation will be 9:3:3:1. Dihybrid cross is a cross that includes two different traits. The phenotypic ratio of the offspring in dihybrid cross is 9:3:3:1. These are: 9 individuals with both dominant traits, 3 individuals with the first dominant trait and the second recessive trait, 3 individuals with the first recessive trait and the first recessive trait, and 1 individual with both recessive traits.
