Find the genotypes of individuals | Homework Help

A male fruit fly with red eyes and long wings is mated to a female with brown eyes and short wings.
The F1 offspring consist of red-eyed, long-winged females and red-eyed, short-winged males.
The F1 are intercrossed to produce an F2. Both sexes of the F2 show the following phenotypes in the ratios indicated.
3/8 red eyes, long wings
3/8 red eyes, short wings
1/8 brown eyes, long wings
1/8 brown eyes, short wings.
Use the symbols R and r for eye color, and W and w for wing length. Determine the modes of transmission for the genes controlling eye color and wing length in these flies and answer the following questions.
a. Which forms are dominant? (circle one form of each gene) red or brown long or short
b. What are the genotypes of the following individuals? (fill in the blanks) Parental males: ___________ Parental females: _________ F1 males: ___________ F1 females: __________
