The # F_2# generation would have 1/4 GG 1/2 Gg and 1/4 gg

Explanation:

Assuming that the the flies with the grey bodies were homozygous
That is GG and the black bodies were homozygous gg ( a safe assumption since it appears black or g is recessive) All of the #F_1#
generation would be a hybrid heterozygous form of Gg

When you cross the #F_1# hybrids with each other you are crossing a Gg with a Gg. The punnett square will give 1 square with both GG
1 square with both gg and 2 squares with Gg
