Cleavage in most animals segregates cells containing germ plasm from other cells. Oskar is sufficient to recruit the other genes to form functional germ plasm. Germ plasm has been studied in detail in Drosophila. Post-translationally, in "Drosophila", Vasa protein is localized to the pole plasm during embryonic development. The first resistant germ plasm was identified in Israel, by Reuveni et al. Another enzyme, fat facets, may further stabilize Vasa in the pole plasm. In Nazi rhetoric, these concerns were connected to racist theories about the "German germ plasm". The results were consistent with Weismann's germ plasm theory. Genetic information cannot pass from soma to germ plasm and on to the next generation. The basis for the complete rejection of Lamarckism was Weismann's germ plasm theory. Germ plasm theory, on the other hand, does so effortlessly. The result can be seen in his "Echo Plasm". Another limiting factor is "Plasm". However, he devises an attempt to overthrow the rulers of Plasm. Though Defiant changed the title to "Warriors of Plasm", Marvel continued its lawsuit.
