The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be 9:3:3:1. This ratio is obtained when two heterozygous individuals are crossed for two traits that are independently inherited. The ratio represents the different combinations of phenotypes that can arise from the cross.

9:3:3:1 ratio of dihybrid cross
Phenotypic ratio pertains to the number of offspring with a particular trait or combination of traits. This can be determined by the genotypes in a person, animal, or plant.

dihybrid cross
representation of genotypes of a pair of contrasting traits of a character in the form of ratio is referred as genetic ratio. in this ratio the three different genotypes are represented- homozygous dominant genotype:heterozygote genotype:homozygous recessive genotype in case of a monohybrid cross ( either normal cross,reciprocal crosses of Mendel or back cross or test cross ratios) and for dihybrid crosses- dominant genotype:recombinant genotypes:recessive genotypes are represented. For instance monohybrid genotypic ratio is 1:2:1 and back cross/test cross ratio-1:1 For dihybrid genotypic ratio 1:2:2:4:1:2:1:2:1 It may differ in different cases according to T.H.Morgan.Bateson, punnet, Garrod etc.
