    White eyes are caused by an X-linked recessive allele. An affected female will have the genotype w/w while the male will have the genotype w/O.

    Vestigial wings are caused by an autosome recessive allele. Affected individuals are vg/vg while carriers are vg/+ and normal wings are +/+.

    Let's start with a white eyed female with normal wings (X<w>/X<w> vg+/vg+) and a normal eyed vestigial winged male (X<w+>/O vg/vg)

    X<w>vg+ ...
