Question 2

The genes for light eyes (lt; light) and straw bristles (stw; straw) are tightly linked on chromosome 2 in Drosophila melanogaster.

There is no maternal effect associated with the straw locus. Give the phenotypes of the offspring from the following crosses.
FemaleMale
Cross #1:lt stw/lt stwlt+stw+/lt stw
