The data set below summarizes F2 numbers from an F1 cross arising from two, true-breeding
Drosophila strains (P generation), which differ with respect to two mutant traits. The genes can
be autosomal or X-linked and the mutant alleles can be dominant or recessive or incompletely or
co-dominant.

Based on the data above, please complete the following questions:
Develop a genetic hypothesis regarding the mode of inheritance of each allele from the data set
above. Explain how the data set supports your genetic hypothesis for each trait. (ex. why you
think a trait is recessive vs dominant or X-linked vs autosomal. Comment on the observed ratios
or differences or similarities in male and female numbers and explain how these provide support
for your hypotheses).
Assign genetic symbols to the four alleles involved, make sure that the notations are informative.
Use upper case to indicate dominance and lowercase to indicate recessivenesses. The use of a
superscript + only tells the reader the allele is wildtype and not its dominance status.
Use Punnett squares for each F1 cross and resulting F2 generation to demonstrate how the data
supports your genetic hypotheses. Analyze each gene separately.
Indicate the expected (predicted) phenotypic numbers for the F2 generation from your Punnett
square constructed in the question above (#3).
