Q.
Mendel's work was rediscovered by three scientists in the year
Principles of Inheritance and Variation
Solution:
Gregor Johann Mendel $(1822-84)$ is known as Father of Genetics. Mendel's work remained un-noticed and unappreciated for some $34$ years. In $1900$, three workers independently rediscovered the principles of heredity already worked out by Mendel. They were Hugo de Vries of Holland, Carl Correns of Germany and Erich von Tschermak of Austria.
