This epoch-making book presented evidence that genes were arranged linearly on chromosomes, and that the Mendelian laws could be shown to be based on observable events occurring in cells. The group also showed that heredity could be studied rigorously and quantitatively. Morgan was awarded the Nobel Prize for Physiology or Medicine in 1933 ['for his discoveries concerning the role played by the chromosome in heredity']." Hermann J. Muller was awarded the Nobel Prize for Physiology or Medicine in 1946 "for the discovery of the production of mutations by means of X-ray irradiation". The first printing has the date 1915 printed on the title page. The date was removed from the title page in later printings and a number, such as 2, was printed on the verso of the title page to indicate the printing.
