Extracted text: Drosophila can have 1, 2, or 3 stripes on their body. From previous experiments, you suspect that there are 2 genes (Gene C and Gene D) that control the number of stripes. A recent published paper described a similar stripe pattern in bees. Furthermore, in bees, Gene C is recessively epistatic to Gene D, are on different chromosomes, and the order of function is the following: C D 3 stripes → 2 stripes 1 stripe You therefore set out to test the hypothesis that Gene Cis also recessively epistatic to Gene D in Drosophila. To do so, you begin by crossing pure breeding 1-striped drosophila with pure breeding 3-stripped drosophila. To statically test your hypothesis, you proceed to perform a chi-square analysis on data obtained from the F1 X F1 cross. Using your hypothesis as your basis to analyze the results, fill the table below. Note: You do not have to calculate the chi-square or make a conclusion. Just fill the table. Observed Еxpected Нуpothesized Phenotypic ratio Phenotypes F2 numbers 1 stripe 15 2 stripes 29 3 stripes 136
