Question

What did experiment by Weismann prove?

Answer 1

The Germplasm continuity theory:

1. August Weismann proved the germ plasm continuity theory by the experiment.
2. According to his hypothesis, germplasm is the hereditary material passed down from generation to generation and is separate from all other cells in the body.
3. Germplasm is an essential component of germ cells(eggs and sperm).
4. Only the features that affect germ cells are passed down in this manner.
5. Somatic cell protoplasm is not, and hence acquired features cannot be transferred down to the next generation.
6. Weismann demonstrated this by removing mice's tails and allowing them to reproduce for up to 22 generations.
7. He noticed that tailless mice produced offspring with tails
