In Drosophila melanogaster, cinnabar eye (cn)and vestigial wing (vg) are simple recessive traits.a A male pure line wild type eye ,vestigial wing cross with female pure line cinnabar eye, wild type wing . F1female, heterozygous for both genes, was crossed with a male with cinnabar eyes and vestigial wings. The offspring resulting from this cross are listed in below class

I Wild type

II Cinnabar eye, wild-type wing

III Wild-type eye, vestigial wing
