1. The following experiment was undertaken to determine how eye colour is inherited in the fruit fly (Drosophila melanogaster)
PI: homozygous red-eyed males X homozygous white-eyed females
all had red eyes
FI progeny (red eyes) was interbred
white-eyed progeny red-eyed progeny

a. What do these results tell you about the type of inheritance that is present at this locus?
b. What are the genotypes of the parents in the first cross (PI)?
c. What is the genotype of the Fl progeny?
d. What are the phenotypes of the F2 progeny?
e. What is the raåo of the phenotypes in the F2 progeny?
f. What is the proportion of homozygous red-eyed individuals in the F2 progeny?
