Thomas H. Morgan (1866-1945), geneticists of the United States of America, studied the chromosome of Pamace Fly and won Nobel Prize for Medicine in 1933. Hermann Joseph Muller (1890-1967) , Morgan's pupil, found that X-radiation could cause mutation by an experiment of the X-radiation for the Drosophila artificially and won Nobel Prize for Medicine in 1946.
