Analysis Of Gregor Mendel s The Mid 1800 S - 1182 Words

Before Gregor Mendel’s discoveries in the mid 1800’s, most people had no clear idea as to why their children, and grandchildren, looked like them! Most people assumed that because the child was in their family, and created by them, that familiar looking offspring just simply happened. Gregor Mendel put all that guessing to rest. Mendel did experiments on two different colored pea plants. In the first test, he mixed a purple flowered pea plant, and a white flowered pea plant. He let these plants fertilize and have off spring. These two plants were known as the Parent generation (P Generation). The offspring they produced were known as the F1 Generation. The P Generation created an F1 Generation that was all purple pea plants. Mendel then bred a new generation of pea plants ONLY breeding plants with themselves. This new generation was known as the F2 Generation. Within the F2 Generation, the white flowered pea plants began to show back up. The ratio of purple flowered pea plants, to white flowered pea plants was a 3:1 ratio. Mendel also noted that the purple and white color had not been blended; the white color was just purely masked by the purple color in the F1 Generation. Mendel was then able to make conclusions about simple breeding. He called the purple flowers dominant, because they were more frequent than the white flowers. He called the white flowers recessive, because they were less frequent than the purple flowers. Therefore he concluded that the purple flowers wereShow MoreRelatedGenetically Modified Organisms And Human Health3263 Words   |  14 Pagesadopts a broader definition with regard to GMO foods: an organism whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism (WHO).
