  2. Gregor Mendel 1822 - 1884 Clarence McClung shows that female mammals have two X chromosomes and males have one X and one Y. Walter Sutton states that chromosomes are paired and may be the carriers of heredity. 1905 AD 1900 AD 1902 AD Higo Marie DeVries, Karl Franz Joseph Correns and Erich Tschermat von Seysenegg rediscover Gregor Mendel's work on genetics, which has been ignored for 40 years. They each rediscover his laws for themselves, search the literature and when they find Mendel’s work they each, in a very unselfish gesture, give Mendel the credit.

  3. Thomas Hurst Morgan starts working on fruit flies to prove that chromosomes have a role in hereditary and to confirm mutation theory. This work will lead to a much deeper understanding of the mechanisms of hereditary. 1944 AD 1907 AD Oswald Avery, Colin MacLeod and Maclyn McCarthy show that DNA is the hereditary material for most living organisms.
