You have identified a new species of Drosphila and you have mapped several genes to
specificchromosomes. In 2 point crosses, you found that the white
eye (w) gene and the spotted body (s) genesare 10 map units apart
on the X chromosome. White eyes (w) is recessive to red eyes (w+)
and spotted body (s) is recessive to solid (s+). You cross a true
breeding white-eyed female fruit fly with solid colourto a red-eyed
male fruitfly with a spotted body. You then self-cross the F1
generation to generate F2 progeny. Cross the parents and find the
F1 and F2 generation. I know that the answer is ws+/ws+ x
w+s/Y for the parentals, but how was this found? Please explain how
in detail and if possible with a Punnett square for both
generations.
