Dihybrid crosses can be conducted with two organisms that are heterozygous for two different traits: SsYy x SaYy for example. Which genotypic ratio shows that genes in dihybrid crosses are inherited according to the principle of independent assortment

OA 25:25:25:25

OB. 50:50

C 3:1

D 9:3:3:1

D. 9:3:3:1

This genotypic ratio demonstrates independent assortment, as it shows all possible combinations of alleles resulting from the dihybrid cross.
