Theory of Continuity of Germplasm:
The scientist who gave the Theory of Continuity of Germplasm is August Weismann.

Explanation:
- August Weismann was a German biologist who proposed the Theory of Continuity of Germplasm in the late 19th century.
- According to this theory, there is a continuous and undivided germplasm that is passed from one generation to the next.
- Germplasm refers to the genetic material present in the germ cells, which are responsible for the transmission of traits from parents to offspring.
- Weismann's theory contradicted the theory of pangenesis proposed by Charles Darwin, which suggested that gemmules (tiny particles) from all parts of the body contribute to the formation of the germ cells.
- Weismann believed that germ cells are distinct and separate from the somatic cells of the body. He proposed that the germ cells are not influenced by the changes occurring in the somatic cells during an organism's lifetime.
- According to Weismann, only variations occurring in the germ cells can be inherited by the next generation, while the somatic cells do not contribute to the hereditary material.
- He conducted experiments on mice to support his theory. He observed that mice with their tails cut off continued to produce offspring with intact tails, proving that acquired characteristics are not inherited.
- Weismann's theory of the continuity of germplasm laid the foundation for the modern understanding of genetics and inheritance.
- His work supported the idea that genetic information is passed on through the germ cells and is not influenced by the environment or acquired traits during an organism's lifetime.

In conclusion, August Weismann gave the Theory of Continuity of Germplasm, which proposed that the germ cells are distinct from the somatic cells and only variations occurring in the germ cells can be inherited. This theory contradicted the idea of pangenesis proposed by Darwin and contributed to our understanding of genetics and inheritance.
