1. White eyes can be due to the combination of two mutations which eliminate both pigment types normally found in the Drosophila eye. assume that your flies have the two which are autosomal, recessive, and not linked.

a. What are the genotypes of the P generation? Based on the above information, you should be able to determine which two genes are involved.

b. Write the genotypes of the expected F1 progeny.

c. Write the Punnet square showing the correctly notated genotypes expected in the F2 progeny. (Be careful here! Remember that maternal and paternal contributions are noted specifically even if certain genotypes are ultimately equivalent.)

d. What are the phenotypes AND phenotypic ratios expected in the F2 progeny?

e. Write the combined null hypothesis-prediction statement for this pattern

f. If your class scored 336 total flies, how many of each phenotype would you expect to see (assuming a perfect system)?
