Given reason why acuired characters are not inherited.

Explanation

The acquired characters appear in an individual because of his/her response to the external stimuli. These traits develop because of constant exposure to a certain stimulus and the resultant response by the individual. Let us take the example of a wrestler. The wrestler develops good physique because of continuous exercise and suitable diet. Given proper exposure and opportunities, the wrestler may be able to excel in his chosen field. But this does not mean that the son of the wrestler would do equally well in wrestling. He may end up being a cricketer or a film star. Acquired characters do not bring any change in the germ cells. Hence, acquired characters are not inherited from one generation to the next generation.
