Weismannismthe theory, now considerably modified, which proposes that the germ cells are set apart at an early stage of the development and are uninfluenced by characteristics acquired during life. The known action of chemicals and physical factors on chromosomes has resulted in modification of the theory into the CENTRAL DOGMA. The theory is named after the German biologist August Weismann (1834–1914).
