When I worked with Thomas Hunt Morgan in the early 1900s, we occasionally found mutant flies – including the famous white-eyed fly. We knew the mutants must be due to spontaneous mutations in genes.
Mar 7, 2017 · Hermann Joseph Muller conducted three experiments in 1926 and 1927 that demonstrated that exposure to x-rays, a form of high-energy radiation, can cause genetic mutations, changes to an organism's genome, particularly in egg and sperm cells. In his experiments, Muller exposed fruit flies (Drosophila) to x-rays, mated the flies, and observed the ...
May 18, 2017 · His experiments were a part of his doctoral thesis advised by Thomas Hunt Morgan in New York, New York. In his experiments, Bridges studied Drosophila, the common fruit fly, and by doing so showed that a process called nondisjunction caused chromosomes, under some circumstances, to fail to separate when forming sperm and egg cells ...
(a) Thomas Hunt Morgan initially set out trying to discover if a new fruit fly species would result from a large-scale mutation. What did he actually discover? (b) Scientific inquiry is a dynamic process. It should build on the findings of others and should not be approached with any bias. How did Morgan's work demonstrate this principle?

Although known best for his studies in heredity with the small vinegar fly Drosophila melanogaster (often called fruit fly), Morgan contributed significantly to descriptive and experimental embryology, cytology, and, to a lesser extent, evolutionary theory.
Mar 30, 2015 · Thomas Hunt Morgan struck gold when he decided to use the fruit fly as a model. He and his students pushed this prolific little animal to great success. They furthered Mendel’s work to discover ...
