Germ-plasm The Germ-Plasm book, 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.

Friedrich Leopold August Weismann published Das Keimplasma: eine Theorie der Vererbung (The Germ-Plasm: a Theory of Heredity, hereafter The Germ-Plasm) while working at the University of Freiburg in Freiburg, Germany in William N. Parker, a professor in the University College of South Wales and Monmouthshire in Cardiff, UK, translated The Germ-Plasm into English in The germ plasm theory was first proposed by August Weismann in and it states that multicellular organisms contain germ cells.

These cells provide heritable information that can be transmittable information. Somatic cells would then carry out the daily functions of the body.

In germ plasm theory, only the places where heritable information needs to.

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. Compared with the essay, The Germ-Plasm provided hereditary explanations for developmental and evolutionary phenomena.

The Germ-Plasm has an introduction and four parts, divided into fourteen chapters. In the Introduction of The Germ-Plasm, Weismann provides a brief history of hereditary theories before the germ-plasm theory.

ADVERTISEMENTS: Weismann’s Germ Plasm Theory: Main Points, Objections and Significance. August Weismann () was a neo-Darwinian biologist who proposed the germplasm theory in his book Das Keimplasma. ADVERTISEMENTS: He said that variations are of two types. Some are congenital i.e., organisms are born with them.

Others are acquired during the life time of a [ ]. First edition in English of Weismann’s complete theory of the germ plasm. August Weismann, in his time considered the first original evolutionist after Darwin (Mendel had not yet been rediscovered), “actually diverted the study of evolution into the pathway which has led on to the great modern advances in the field of genetics” (Eiseley.

Thus was born the theory of the germ plasm, which he embodied in a book first published in German in and in English in Its essence was the notion that all living things contain a special hereditary substance. The general idea is still accepted as valid today, though in place of germ plasm one speaks of chromosomes, genes, and DNA.

The term Keimplasma (germ plasm) was first used by the German biologist August Weismann (–), and described in his book Das Keimplasma: eine Theorie der Vererbung (The Germ Plasm: a theory of inheritance). [1]. Book digitized by Google from the library of the University of Michigan and uploaded to the Internet Archive by user : The germ plasm was the material of heredity located in the chromosomes; it contained the information or program (as we would call it today) for building the new organism.

However, Weismann insisted that it was completely isolated from the body or soma that surrounded it so that any changes taking place in the parents' bodies could not be.

The germ plasm is the living part of a cell that has divided from a somatic cell and contains half of the chromosomes necessary for sexual reproduction with a cell of the opposite sex to form a new individual which contains the genetic traits of both parents. Germ-plasm theory is a concept of the physical basis of heredity, put forward by August Weismann.

germ plasm bank An establishment concerned primarily with the conservation of hereditary genetic material which may be lost through the process of genetic erosion. Germ plasm loss is a major concern in Asia, parts of Africa, southern Europe, and countries bordering the Mediterranean, where antiquated cultivars are rapidly replaced by new varieties.

With the loss of older cultivars, qualities.Dr Johnson said: "Within our new theory of evolution pluripotency came first and so germ plasm would have to have evolved independently several times in species within the branches of the tree, for example in frogs and many fish.This chapter focuses on August Weismann's theory of the germ-plasm.

It is argued that both Weismann's failure to conceive of any alternative to the disintegration of the idioplasm as the mechanism of ontogenetic differentiation and nuclear control, and his failure to conceive of any genuinely facultative capacity on the part of the germ-plasm suggest that Weismann never conceived of the quite.
