1. In Drosophila melanogaster (Fruit fly), black body (b) is recessive to gray body (b+), purple eyes (pr) is recessive to red eyes (pr+) and vestigial wings vg is recessive to normal wings (vg+). The loci coding for these traits are linked with the following map distances



The interference among these genes is 0.5. A fly with black body, purple eyes and vestigial wings is crossed with a fly homozygous for gray body, red eyes and normal wings. The female progeny are then crossed with males that have black bodies, purple eyes and vestigial wings. If 1000 progeny are produced from this testcross, what will be the phenotypes and proportions of the progeny?
