Did research on what males and females look like. We observed the frozen flies.
On the first week we used fly nap as an anesthetic for the flies and waiting for them to fall asleep. We sexed the flies and put 10 male and 10 female into a tube. We provided them with food and a sponge to allow oxygen to flow in and out of the tube. The males were Wild type and the Females were type C.
After one week we came back to several pupa larva and parents that were active. We once again sedated them with fly nap and as they slowed down we took them out and examined them as well as any babies that were born. There was larvae that was spotted making its way up the walls of the tube, possibly prepared to become a pupa.
(the P1 was paired on 3/9 and they …show more content…
We do not have enough information to call it an Autosomal/Sex-Linked inheritance pattern. 75% are type C so it is dominant.

It can show how the different phenotypes are apply and how something can be proved by the punnett squares.
What was determined and what can you conclude from this work?
We can determine that the Dominant and Recessive reproduction is true in this scenario and that you need a lot more information to figure out whether it is autosomal/sexlinked. From the data we figured out that the wild type if dominant and Type C is recessive. We rejected the null hypothesis and we think that our overall idea for the hypothesis is wrong.
If your observed data did not match your expected results, can you think of any explanations for this? We think from the Chi-square calculations that the wild type is not dominant to the wild type because we do not have enough information to determine that yet. An explanation could have been the misgendering of flies, dropping them, miscounting, accidently getting them stuck in the medium, or adding so much flynap that they died.
Were there any errors made, and how might they have affected your results?
One time I put the tube up right when the flies were sleeping. Several got stuck to the food at the bottom but we salvaged enough to start a new
