The principles used in this report are the same that would apply for any species. The purpose of the exercise was to examine and learn the changes and the mutations which are passed down from generation to generation. By observing the genetic variation in the flies, we were able to see the way it affects future generations. .
The method is simple; allow the flies to do the reproduction thing, then we knock them out by inserting a small pipe-cleaner with "Fly-Nap" on it into their habitat. Once the flies stopped moving, we opened their tube, poured them out, and meticulously counted them under a dissection microscope. We also observed their sex and sex-related traits and recorded them. Once we had used them for our evil purposes, we disposed of them accordingly by pouring the pathetic flies into a jar of alcohol. Our flies had varied a lot, but we may have been able to determine dominate and recessive genes for each. We counted our flies twice, and came up with a total of 160. For our results to be precise, we had to allow for P-1 mutations. We did a fly count about twice a week for two weeks.
Out F-1 phenotypes and genotypes were non-typical. The phenotypes were yellow/tan body-white eyes, and yellow/tan body-red eyes. We did get two white body-white eyes, which may have been recessive because they were only males. This has no affect on Generation Two or its white body, red/white eyed population. The genotypes are all of the above listed traits. We observed the F-2 Generation's mutations. These mutations were new and unique to the species we were working with. The traits included yellow/brown bodies, white/red eyes that were in the majority last time for both male and female. The white bodied flies were almost completely disinherited in the future generations. They are probably white because few carry the gene.
We observed many strange traits throughout our experiments, but our expected ratios were 35% with white eyes/yellow bodies.
