Answer 2

Answer:

Option A is the correct answer

Some points on Weismann's Theory of Continuity of Germplasm:-

1. Weismann cut off the tails of rats for as many as 22 generations and allowed them to breed, but tailless or reduced tailed rats were never born.

2. On the basis of this experiment Weismann proposed the theory of continuity of germplasm.

3. According to this theory Two types of protoplasms are present in an organism, germplasm and somatoplasm.

4. There will be continuity of germplasm & the variations influences the germ cells and those are only inherited but the somatoplasm is not transmitted to the next generation, hence it does not carry variations to next generation.
