F1 progeny is self crossed given that the two genes are on different chromosomes which means they show independent assortment:

AaBb X AaBb =

A_B_ = normal body, normal eyes = 9

aaB_ = ebony body, normal eyes = 3

A_bb = normal body, eyeless = 3

aabb = ebony body, eyeless = 1

Hence the ratio is 9 : 3 : 3 : 1
