342343 The question refers to eye colour in fruit fly. In this sex-linked trait, the allele for red eye is dominant to that for white eye.
If a red-eyed male is crossed with a white-eyed female, their offsprings will occur in the ratio

1 1 red-eyed female : 1 red-eyed male
2 1 red -eyed female : 1 white-eyed male
3 1 white-eyed female : 1 red-eyed male
4 1 red-eyed female 1 white-eyed female : 1 red-eyed male : 1 white-eyed male.
