The history of fruit flies is considered a tradition. Research of these flies initially entered labs 100 years ago. Thomas Hunt Morgan‚ who lived from 1866 to 1945‚ was the founder of drosophila genetics. Thomas preformed his research in Morgan lab at the Columbia University in 1910. Here was when they found a famous mutation‚ know as the white-eyed fly. Quite an accomplishment was this discovery‚ but the end of the 1980’s there were 3‚000+-recorded mutations. Now drosophila is very popular; so popular

from it. Papayas do not have branches. The papaya fruit is pear-shaped with a bright golden-yellow skin. The flesh of the fruit is a brighter orange-yellow‚ juicy and silky smooth‚ with a sweet and sour flavor. The shiny gray or black seeds in the interior of the fruit have a peppery taste and are edible‚ although they are usually discarded. The papaya is an extraordinarily useful plant. In the tropics around the world papaya is the breakfast fruit‚ served either green or ripe. The juice is a popular

The Beginning of a Long Battle In his article “Insensible Perspiration and Oily Vegetable Humor: An Eighteenth- Century Controversy Over Vegetarianism‚” Ken Albala makes an expository statement about the wondrous vegetarian diet advocated by Italian physician Antonio Cocchi and the arguments made against him by two other Italian physicians‚ all of which ultimately contribute to humanity’s perpetual search for the perfect diet. I found this article amusing‚ as most of the scientific evidence presented

Strange Fruit The poem “Strange Fruit” was written by Abel Meeropol. The poem was published on April 20‚ 1937. The authors motivation to write the poem “Strange Fruit” was that he was very disturbed with the racism of the time and when he saw the photo of the two black teenagers that had been lynched it “‘put him over the edge.”’(Elizabeth Blair). My overall response to the poem is that it makes me sick to picture what Billie Holiday painted a clear picture of‚ and to see the picture of the teens

The purpose of this experiment was to determine the F1 genotype of fruit fly traits using the phenotypic ratio of the F2 generation and to express these results of the unknown cross through a Chi-square model and Mendelian genetics. After the experiment‚ it was found that the parents held a heterozygous genotype through using the Chi-square model‚ and that the observed and expected values fall within the Chi-squared value which also falls into the p-value. The Chi-squared value was 5.64‚ the degrees
