Fly Lab Complete the following for full credit on this lab. When submitting the “Lab Notes”, be sure to include headings and descriptions so that your data can be easily linked to the correct assignment. 0.1 Please identify any “lab partners” you had for this lab activity. None MAKE SURE THAT YOUR ANSWERS ARE YOUR OWN AND REFLECT YOUR UNDERSTANDING. YOUR ANSWERS SHOULD NOT BE IDENTICAL TO YOUR LAB PARTNERS ANSWERS. Assignments for non-majors NOTE: always select the “Ignore Sex” option on the “Summary of Results” and the “Chi-Square Analysis” screens! Assignment 1: Getting to Know FlyLab: Performing Monohybrid, Dihybrid, and Trihybrid Crosses Create a monohybrid cross between a wild-type female fly and a male fly with sepia eyes. These two flies represent the parental generation (P generation) for your cross. 1.1 Based on what you know about the principles of Mendelian genetics, predict the phenotypic ratio that you would expect to see for the F 1 offspring of this cross and describe the phenotype of each fly. I would predict that there will be about 500 females and males with the sepia eyes and about 500 females and males with wild eyes. 1.2 Are the phenotypes of the F 1 offspring what you would have predicted for this cross? Why or why not? The phenotypes of the F1 offspring were not what I predicted for this cross. The Wild eye color was the dominant Allele in the cross and the split between male and female was about even. Set up a cross between two F 1 offspring to produce an F 2 generation. 1.3 Examine the phenotypes of the offspring produced and save the results to your lab notes by clicking on the Results Summary button on the lower left side of the Mate view. Note observed phenotypic ratios of the F 2 offspring. The Phenotypic ratios of the F2 offspring were about same as the F1 offspring. They were split at 377 Female with wild eye color, and 365 Male with wild eye color. The number of females with sepia eyes was 118, and the number of males with sepia eyes was 123. Perform a chi-square analysis.

1. 4 Note the level of significance displayed with a recommendation to either reject or not reject your hypothesis. What was the recommendation from the chi-square test? Was your ratio accepted or rejected? I chose the ratio 4:1. The recommendation from the chi-square was to reject my hypothesis. The level of significance was 0.0004. If your ratio was rejected, repeat the chi-square analysis with a new ratio until you discover a ratio that will not be rejected. 1.5 What did you discover to be the correct phenotypic ratio for this experiment? Was this what you expected? Why or why not? What do the results of this experiment tell you about the dominance or recessiveness of the sepia allele for eye color? The correct phenotypic ratio was 3:1. It was not what I expected at first but after testing my hypothesis, I realized that would be the most logical choice. The results of this experiment tell you that the Wild eye color allele is the dominant allele and the sepia
