Mendels Peas and Hawkweeds :: Heredity Genes Mendel Research Essays

Mendels Peas and Hawkweeds plant life Cited MissingMany Scientists have contributed to the field of transmitteds. Yet the groundwork for todays juvenile genetics can be found in the work make by one man, Gregor Mendel. While there were many scientists who tried to say the same questions before him, none were able to come to the palmy conclusions he did. Before Mendels experiments, many other theories had been in place to answer the questions approximately why we look like our parents. Many of these beliefs were myths, and the true reasons behind heredity were not sought, because creation was the belief of the majority of people. Some of these beliefs include The guess of preformation theory (Bowler, 2), in which it was believed that the embryo grew from a perfectly formed toy already present in the mothers womb ( or the fathers sperm). (Bowler, 2) Another theory was that of blending inheritance in which the offsprings characters were always intermediate between those of its parents. (Bowler, 3) It was in the time of these theories that Mendel did his work, which was pink-slipped as stated in the story. Mendel was a monk who taught in the monastery, and he did his experiments in the garden outside the monastery while teaching as verbalize in the book. His main focus was on the garden pea, Pisum sativum. single peculiarity of pea reproduction is that the petals of the flower close down Tightly, preventing pollen grains from go in or leaving. This enforces a system of self-fertilization, in which sperm and eggs from a particular flower Unite with each other to produce seeds. As a result, individual pee strains are Highly inbred, displaying little, if any genetic variation from one generation to The next. Because of this uniformity, we say that such strains are true-breeding. ( Snustad, 42) In his experiments, Mendel tested many different traits. Among them were the following traits and the frequencies each appeared in Mendel was successful in his ex periments, because he tested one trait at a time, as compared to other scientists who tried to follow multiple traits. This is what allowed him to be successful, although with what we get it on now, it is easier to follow many traits at a time. In his first repair of experiments, he crossed tall varieties with dwarf varieties. To do this, He conservatively removed the anthers from one variety before its pollen had matured and then apply pollen from the other variety to the stigma.
