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.
dihybrid cross
In a fully heterozygous dihybrid cross, each parent carries two different alleles for each of the two traits being studied. The resulting offspring will have a 9:3:3:1 phenotypic ratio due to independent assortment of alleles. This type of cross can help to determine the potential genotypes and phenotypes of future generations.
A dihybrid cross results in 16 boxes for the offspring. For example, the cross RrDd X RrDd is shown below:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
A dihybrid cross, which involves the inheritance of two different traits, can predict the genetic outcomes for two characteristics in offspring. This type of cross allows for the study of independent assortment and genetic recombination.

In a dihybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively. In a monohybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively.

Science deals with the term dihybrid cross and it is a term that explains how two different colored parents end up with the color pattern of their offspring. The law of independent segregation is explain by dihybrid cross.
