August Weismann
Explanation
Germplasm theory was proposed by August Weismann, a German biologist, in the late 19th century. This theory suggested that genetic information is passed from generation to generation through the germ cells (sperm and egg cells) and that the somatic cells (body cells) do not contribute to the transmission of genetic information to the next generation. This idea was influential in shaping early understanding of genetics and inheritance.
