The document's social and political ideals were proposed by Jefferson before the inauguration of Washington. He was inspired by the Enlightenment ideals of the sanctity of the individual, as well as by the writings of Locke and Montesquieu. The committee initially thought that Adams should write the document, but Adams persuaded the committee to choose Jefferson.
Food substance that can be put in tubes Magnifying lens Procedure Leave a fruit out in the open for 5 days. Two types of fruit flies should start to appear day by day: These are the only traits tested. Isolate one red eyed female virgin fly and one white eyed male fly in a suitable mating capacity which can be a tube with appropriate conditions.
When the larvae have been created, take out the parents to prevent mating with the first generation. This would convolute the experiment if the parents were unnoticeably allowed to mate with the F2 generation.
When the flies have grown up freeze them to immobilize them for a little while. Then take them out onto a clean surface by gently shaking the tube downward.
Make sure they are all out because each and every one of the flies can alter the outcome of the results. Separate the F2 generation by eye color and gender. Make a chart or a list that shows the exact number of flies in each gender group and separate them again with the color of their eyes.
Why did this come out the way it did? What were the key factors that influenced the outcomes? Then mate a male with a female from the F2 generation in a closed tube with food substances inside.
Make sure that they are only from the F2 generation. After the female lays her eggs remove the parents from the tube to thwart future mating with the F3 generation. Wait about 14 to 21 days for the flies to grow into full adults.
Once the larvae have grown into adults, freeze the tube again to immobilize them for a while. Then separate them again by gender and eye color as before. Observations Male flies have a small black comb like fragment on their legs unlike the female fly.
Female flies a visibly bigger than male flies. The flies in the F2 generation were all red eyed but were not all female After the dihybrid cross, there started to be more white flies.
Analysis It was observed a small but discrete variation known as white-eye in a single male fly in one of the bottles. I bred the fly with normal red-eyed females. All of the offspring F1 were red-eyed. Brother—sister matings among the F1 generation produced a second generation F2 with some white-eyed flies, all of which were males.
To explain this curious phenomenon, I developed the hypothesis of sex-limited—today called sex-linked—characters, which I assumed were part of the now called X-chromosome of females. Other genetic variations arose in my stock, many of which were also found to be sex-linked.What Is Life?
