The Germ-plasm: A Theory Of Heredity Paperback – September 2, by August Weismann (Author)Author: August Weismann. In his germ plasm theory, proposed in and detailed in his book, The Germ-Plasm: A Theory of Heredity, Weismann emphasized the stability of germ plasm (hereditary material, now called genes) that was transmitted, without change, from generation to generation.

In his theory, the environment had little, if any, effect on the germ plasm, even if the environment altered external body characteristics. His main contribution involved his Germ Plasm Theory, at one time also known as Weismannism, according to which inheritance (in a multicellular organism) only takes place by means of the germ cells - the gametes such as egg cells and sperm cells.

Other cells of the body - somatic cells - do not function as agents of heredity.

The Germ-Plasm compiled Weismann's theoretical work and analyses of other biologists' experimental work in the s, and it provided a framework to study development, evolution and heredity. Germ-plasm theory, concept of the physical basis of heredity expressed by the 19th-century biologist August Weismann (q.v.).

According to his theory, germ plasm, which is independent from all other cells of the body (somatoplasm), is the essential element of germ cells (eggs and sperm) and is the hereditary material that is passed from generation to generation. In the germ plasm theory, inheritance in a multicellular organism only takes place by means of the germ cells: the gametes, such as egg cells and sperm cells.
