    Give reasons why acquired characters are not inherited.

Answer:

                  Acquired characters do not produce change in the genes (or DNA) of germ cells, so they cannot be inherited. e.g..If tails of mice are cut in first generation, and then breeding is done, the new mice born will have full tails. The cut tail of mice is an acquired trait which is never passed on to their progeny. This is because cutting of mice tails does not change the genes of their reproductive cells.
