[6] The Weismann barrier, proposed by August Weismann, is the strict distinction between the "immortal" germ cell lineages producing gametes and "disposable" somatic cells, in contrast to Charles Darwin's proposed pangenesis mechanism for inheritance. In more precise terminology, hereditary information moves only from germline cells to somatic cells (that is, somatic mutations are not inherited Weismann barrier: Cutting off mice tails The idea that germline cells contain information that passes to each generation unaffected by experience and independent of the somatic (body) cells, came to be referred to as the Weismann Barrier, and is frequently quoted as putting a final end to the theory of Lamarck and the inheritance of acquired characteristics. Weismann a exposé le concept dans son livre de 1892 Das Keimplasma: eine Theorie der Vererbung (Le germ Plasm: une théorie de l'héritage). La barrière de Weismann était d'une grande importance à son époque et, entre autres influences, elle bannissait effectivement certains concepts lamarckiens : en particulier, elle rendrait l'héritage lamarckien des changements du corps (le soma and the mammalian germline: the Weismann barrier 1 revisited Davood Sabour and Hans R Scho¨ler1,2 The germline represents a unique cell type that can transmit genetic material to the next generation.

As scientific research has advanced, the persistence of the concept of the barrier has left us with 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 1892. William N. Parker, a professor in the University College of South Wales and Monmouthshire in Cardiff, UK, translated The Germ-Plasm into English in 1893.

[6] Die Weismann-Barriere ist die Hypothese, dass die Übernahme von Informationen erworbener Eigenschaften (sogenannte Modifikationen) in die Erbinformation von Keimzellen unmöglich ist und somit erworbene Eigenschaften nicht vererbbar sind. Sie wurde 1883 von August Weismann formuliert.
