Drosophila Lab Report

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies, I learned that the purpose of breeding them was to test how genetics pass from generation to generation, also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment, the most common fly (or the fly with the highest population) would be the red eyed, winged flies. On day one, my group and I were given four virgin, red eyed, winged, female flies. One of my group members, Brycen, accidently lost two of the flies, and one of them never woke up from being put to sleep. This left us with only one virgin female fly. We were also given four brown
We were excited, until I made a mistake and got all of the F2 generation flies stuck in the median, and the mass majority of the flies died. Luckily though, our instructor, Mrs. Mahan, allowed us to find a group that we felt were near what we may have had. We chose a group, and we had to borrow their data for the rest of the lab. The failure of my group’s lab was entirely my fault, due to the fact that I had not been listening at the time, andI take full responsibility as such. If it weren’t for that, we would not need to be using someone else’s data to finish this project. The other group’s flies did about as good as ours, and we asked if we could borrow their data. They ended up having one hundred and thirty three red eyed, winged flies, twenty two red eyed wingless flies, thirty four brown eyed, winged flies, and five brown eyed, wingless flies. This meant we ended up totaling our number of flies at one hundred and ninety four flies. Hear is a table to show our
