Question

In Drosophila, males from a true-breeding stock with
raspberry-colored eyes were mated to females from a
true-breeding stock with sable-colored bodies. In the
F1 generation, all the females had wild-type eye and
body color, while all the males had wild-type eye
color but sable-colored bodies. When F1 males and
females were mated, the F2 generation was composed
of 216 females with wild-type eyes and bodies, 223
females with wild-type eyes and sable bodies, 191
males with wild-type eyes and sable bodies, 188 males
with raspberry eyes and wild-type bodies, 23 males
with wild-type eyes and bodies, and 27 males with
raspberry eyes and sable bodies. Explain these results
by diagramming the crosses and calculating any relevant map distances
