Since 1900 and the rediscovery of Mendel’s laws, the study of genetics has been a constant Influence upon the development of the biological sciences. Genetics, in its study of heredity and variation, gives a nucleus around which the various phases of fields of biology orbit. It has long been said that "like begets like", but the questions of how life perpetuates itself, how races or species could arise and be maintained and yet show a certain amount of variability could only be answered by a scientific knowledge of the basic factors of life.
