=**Thomas Morgan and Fruit Flies**=

====Thomas Hunt Morgan was born on September 25, 1866 in Lexington Kentucky. Morgan was also known as the Fruit Fly scientist because he did his practices on Fruit Flies. Morgan always wondered everything about genetics. Like what were the inherited factors? Where were these inherited factors located? How were they passed on from one genration to the other. Morgan got all of his answers from a fruit fly. Morgan used red eyed fruit flies and white eyed fruit flies to compare the inheritence. Fruit flies to us are probably pointless. They are annoying and do not really help us as humans in any way. But for Thomas Morgan they were perfect. Fruit flies were perfect becuse they were not expensive to care for, the fruit flies life span was short, so the experiments were quick and the female fruit flies only mated once and layed thousands of eggs, which made it much better for Morgan in the end. His experiments involved fruit flies with "XY" chromosomes, similar to humans. The scientific name for fruit flies is Drosophila melanogaster. The first thing that Morgan studied with these fruit flies was eye color. Thomas Morgan was also the first to find out about Wild Types and Mutant Phenotypes. A wild type is the original. The Mutant Phenotype is the copy, but probably with something different like color or height. Tomas Morgan came up withe the Chromosome Theory of Inheritence. Which says that genes are located on chromosomes. Thomas Hunt Morgan died on December 4, 1945. He was 79 when he died, but he worked all up until his death.====
