Genetics of Drosophilia

The last reason Rosalie Is Ideal for research Is the vanish size and manipulability, since we can easily control them combined with the previous reasons makes them type for research. In our experimental research we attempted to observe genetic changes in three generations of flies. We were given the second generation to observe the traits and record. Our hypothesis is if the drosophila are allowed to interbreed, then genetic variation will occur. Materials 1. Culture ampul of wild-type Drosophila 2. Culture vial A or B or C 3. Spoilsport Alcohol 10%, mall 4. Camels hair dust 5.Thermo-anesthetizes 6. Petri dish Drosophila vials labels with medium 7. 8. Fly morgue 9. Forceps Procedures Part A 1 . Thermally Immobilizers a vial of wild-type Drosophila. Your Instructor will portray the proper Manipulation technique. 2. Observe the flies traits, particularly body features that distinguish males and females, marrow color, and wing size and shape. Record your observations in Table 1 i n the Analysis section. If, at whatever clock during your observations, the flies begin to establish active, re-immobilizers them according to your instructors directions. Part B 1.Obtain a vial off prompt Drosophila mishandle. 2. Record the letter written on your vial In Table 2 In the Analysis sections to help you keep racetrack of which cross you have received. TLS will lad In determining judge results, as well as allow your instructor to identify any problems you may be having and to help correct them. 3. Immobilizers the parental generation of your cross and observe the flies under a stereoscopes. If, at any time during your observations, the flies begin to become active, re-immobilizers them according to your instructors directions. 4. Separate the males from the females.
