ur observations are right,.
it is a test cross with double recessive and for a heterozygote parent in a dihybrid
the offsprings are always in the ratio 1:1:1:1 genotypically and phenotypically.

The answers are right except for 2 things:
1- In the parent genotype you are not using b and s for black body and small wings. You are using g and w respectively which is the correct way to do this but your explanation is wrong: "i did a cross between GgWw x ggww G dominate gray body W normal wings b black body s small wings"

2- The results of a genetic cross are mostly explained in percentage not actual numbers, because what the results show are the possible variations that can happen. Therefore your answers should be: 25% or 1/4 gray with normal wings, 25% or 1/4 gray with small wings, 25% or 1/4 black with normal wings and 25% or 1/4 black with small wings.
