In Drosophila, males from a true-breeding stock with raspberry-colored eyes (instead of normal brownish-red eyes) were mated to females from a true-breeding stock with sable- colored bodies (instead of normal brown bodies). In the F, 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 F, males and females were mated, the F 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 27 males with raspberry eyes and sable bodies. Explain these results by diagramming the crosses and calculating any relevant map distances.

Question
In Drosophila, males from a true-breeding
stock with raspberry-colored eyes (instead of
normal brownish-red eyes) were mated to
females from a true-breeding stock with sable-
colored bodies (instead of normal brown
bodies). In the F, 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 F, males and females were
mated, the F 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
27 males with raspberry eyes and sable bodies.
Explain these results by diagramming the
crosses and calculating any relevant map
distances.
