Gregor Mendel
Gregor Mendel was a person that worked on pea plants. He also discovered the laws of inheritance. The laws inheritance were The Law Segregation, Independent Assortment, Dominance. Segregation a gene pair defines each inherited trait. Independent Assortment Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another. Dominance An organism with alternate forms of a gene will express the form that is dominant. -
FRIEDRICH MIESCHER
Friedrich Miescher isolated the first crude preparation of DNA. He named it nuclein.Miescher was appointed the professor of physiology at the University of Basel.The appointment meant more funds and equipment for research, but it also meant that Miescher had to teach. It was hard for him to teach because of his shyness. SO he thought that it would be awhile before nuclein would be recognized. -
Hugo De Vries
Hugo de Vries was born in Haarlem, Netherlands. He was a Professor of Botany at the University of Amsterdam when he began his genetic experiments with plants in 1880. He completed most of his hybridization experiments without knowing about Mendel's work. Based on his own results, de Vries drew the same conclusions as Mendel.It is now known that de Vries had the right idea, but for the wrong reasons. -
Carl Erich Correns
Carl Correns was born in Münich, Germany, and was orphaned at an early age. In 1885, he entered the University of Münich to study botany. Carl Nägeli, the botanist to whom Mendel wrote about his pea plant experiments, was no longer lecturing at Münich. Nägeli, however, knew Correns' parents and took an interest in him. Him and Mendel worked with each other. -
Thomas Hunt Morgan
Thomas Hunt Morgan established the chromosomal theory of inheritance. As a young boy in Lexington, Kentucky, Morgan loved exploring the countryside collecting samples of wild life and fossils. At the State University of Kentucky, Morgan's course load was heavy in the natural sciences. Morgan had become interested in species variation, and in 1911, he established the "Fly Room".Although Morgan officially retired he continued to work in the lab until his death in 1945. -
Erich Von Tschermak-Seysenegg
Erich von Tschermak-Seysenegg was born in Vienna, Austria. His father was a well-known mineralogist, and his maternal grandfather was the famous botanist, Eduard Fenzl, who taught Gregor Mendel at one point. He studied agriculture at the University of Vienna, and worked on a farm to gain practical agricultural experience.Tschermak graduated with a doctorate from the Halle-Wittenberg University. In 1898, he started doing plant breeding experiments using pea.
