Usage notes

 * The biology term relates to the obsolete theory (Keimplasmatheorie), described in 1892 by German biologist . Through his theory he rejected Lamarckism and proposed what came to be called the Weismann barrier: the principle that germ cells can influence somatic cells, but not vice versa. Weismann's theory was made obsolete by genetics, but the idea that changes acquired during an organism's life cannot affect its offspring is still broadly accepted, albeit within a framework of epigenetic variable expression contrasting with mendelian heredity.
