Day 2: Stock Cultures & Sexing, Part 2

Today's section of the experiment focused on constructing the vials that our first generations of fruit flies would be living in. Using the standard procedure (see research links for exact steps), my lab partner and I made vials for the white-eyed, vestigial, and wild type fruit flies. Then, these individual groups were put under the microscope and evaluated for sex. Males displayed fewer abdominal sections and black splotches on their anterior ends, and females had a greater amount of abdominal sections and no dark coloring on their anterior ends. In each group, there was a fewer amount of females than males.When we finished sexing the flies under the microscope, they were returned to their respective food vials and put in the environmental chamber.
