b) 100%

c) WY

d)  we

e) 50%

Explanation:

In the first generation of crossing of red eyed male with white eyed female, the male become dominant having red eyed offspring . This is due to the presence of recessive allele in the female, so all the offspring produce in F1 generation are 100 % red eyed while in F2 generation half offspring are white and half are red eyed. The recessive allele is represented by small letters while dominant allele is represented by capital letters.
