(A) The theory of continuity of germplasm was proposed by August Weismann $(1834-1914).$August Weismann,a German biologist,was the primary opponent of the theory of inheritance of acquired characters (Lamarckism).He proposed the theory of continuity of germplasm,which states that only characters influencing the germ cells are inherited by the next generation.According to this theory,there is a continuity of germplasm (the genetic material in germ cells),whereas the somatoplasm (the cytoplasm of somatic cells) is not transmitted to the next generation.Therefore,changes acquired by somatic cells (like cutting off a tail) are not passed on to offspring.Weismann demonstrated this by cutting off the tails of mice for $22$ generations,yet tailless mice were never born,thereby proving that Lamarck's theory of inheritance of acquired characters was incorrect.
