A)
Overall, the expected probability and the actual results were for the most part similar, the class totals were a few percent off in most of the crosses. In the first cross, the total percentages were about two percent different than we expected. The class totals, were only about 1 percent different. In the second cross the totals for red eyed males and white eyed females were closed to expected, but the red eyed females and white eyed males were each two percent off from expected. The class totals for this cross weren't close at all. Two of the results were one percent off, and the other were around 8 percent off. There definitely weren't as many red eyed females as expected but there was indeed more white eyed females than expected. The third and final cross was the closest to the expected values for the …show more content…
In every cross we saw this, but I’m going to use the second cross as my example. In the parental generation, all of the flies were either red eyed females or white eyed males. In the next generation, there were a quarter of each type. This showing that some traits are going to be recessive, and masked when the dominant trait will also be present. We know that the fruit flies follow these patterns, because when we all counted them out, mostly were close the expected amount of each type.

The benefits of using fruit flies for our experiment are that they are small in size, and can easily be stored in a classroom setting in school. Statistically we know the flies live best in and around room temperature ,which is where we happened to store them. The traits were trying to spot were easy to identify, which allows us to create accurate data. Another reason that fruit flies worked well for this experiment is that they multiply quickly, so the lab didn’t take many months to finish. Lastly, the traits are very visible because of short time it takes to grow into an adult
