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. This is my data set: Observed Wt females 0 Wt males 305 Naked body females 0 Naked body males 900 Bar eye females 550 Bar eye males 280 Bar eye and naked body females 1750 Bar eye and naked body males 870 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).
