Question

WHAT IS THE GENOTYPIC RATIO OF DIHYBRID
HYBRIDIZATION EXPERIMENTS CONDUCTED BY
MENDEL, WHOSE PHENOTYPIC PROBABILITY IS
9/16?​

Answer 1

Mendel's dihybrid cross was between round yellow and wrinkled green seeds

This lead to the genotypic ratio

1:2:1 :2:4:2:1:2:1

Phenotypic ratio

9:3:3:1

The cross thus gives 16 possible offsprings that can be produced

Out of this the probability of having round yellow seeds is 9/16

So according to the cross it's genotypic ratio is 1:2:2:4

I order to understand this better look at the picture below

I hope this helps
