Detailed explanation-1: -In the experiment, Weismann cut off the tails of 901 mice and their offspring for five generations. If acquired characteristics were heritable, Weismann reasoned, the experimental mice should eventually produce offspring with no tails.

Detailed explanation-2: -Weismann carried out a five-generation experiment in which 68 white mice’s tails were removed and it was reported that no mice were born without a tail or with a shorter tail as a result. Weismann conducted the experiment by removing the tails of 901 mice and their descendants for five generations.

Detailed explanation-3: -Q. Weismann cut off the tails of mice generation after generation, but tails neither disappeared nor shortened, proving that acquired characters are not inherited.

Detailed explanation-4: -Complete Answer:-Weismann proved this theory by performing an experiment in which he cut off the tail of mice for 22 generations and allowed them to breed.

Detailed explanation-5: -August Weismann (1834-1914) was a German evolutionary biologist who proposed a theory of the germ plasm, a precursor to DNA theory. The germ plasm theory suggests that acquired characteristics cannot be inherited.
