Nevertheless, The Germ-Plasm triggered debates among and influenced twentieth century researchers, and Weismann's distinction between germ cells and soma cells became called the Weismann barrier.

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 not only described the existence of the barrier between germinal and somatic cells, but also attempted to demonstrate it experimentally.However, he was not very fortunate in his choice of experimental system.His experiments, in which he cut off the tails of mice over a great many generations to demonstrate that mice would continue to Weismann barrier The Weismann barrier is the principle that hereditary information moves only from genes to body cells but never in reverse. In more precise terminology hereditary information moves only from germline cells to somatic cells (or soma to germline feedback is impossible). The Weissman barrier is the idea, put forth by August Weissman, that mutations in a person’s somatic cells (cells except for egg and sperm cells) would not be passed on to germ cells (egg and sperm cells) and therefore would not be acquired by successive generations. Nevertheless, The Germ-Plasm triggered debates among and influenced twentieth century researchers, and Weismann's distinction between germ cells and soma cells became called the Weismann barrier. The postulate that genetic information cannot pass from the soma to the germline and on to the next generation is known as the Weismann barrier [ 1 ]. During development, germ cells undergo a series of specific events that render them unique and distinct from other cell types.

Weismann therefore rejected the possibility of the inheritance of acquired characteristics, if those Although August Weismann in his 1872 book was correct that the sperm and egg were the only cells to transmit molecular information to the subsequent generation, the concept that somatic cells do not impact the germline (i.e., the Weismann barrier) is incorrect.

However, Weismann's idea of a strict germ line–soma barrier can now be challenged with research on mammalian germ cells using induced pluripotent stem cells (iPSCs) derived from somatic cells.

In more precise terminology hereditary information moves only from germline cells to somatic cells (that is, soma to germline feedback is impossible). This does not refer to the central dogma of molecular biology which states that no sequential information can travel Weismann distinguished somatic cells from germ cells in multi-cellular organisms, and he proposed that changes made to somatic cells cannot be passed to germ cells or to the next generation, a theory later called the Weismann Barrier.
