Solution
The ratio 9:3:3:1 in dihybrid crosses usually indicates independent assortment of alleles. This ratio is the typical phenotypic ratio in the F2 generation of a dihybrid cross which suggests that the two genes in question are assorting independently of each other, meaning they are not linked or close together on the same chromosome. This is a fundamental principle of Mendelian genetics.
