Question

Why are the traits experiences acquired during the entire lifetime of an individual not inherited in the next generation? Explain the reason of this fact with an example

Answer 1

Change in non-reproductive tissues, onaccount of acquired traits, cannot be passed on to the DNA of the germ cells. Therefore, experience gained ortraits acquired during the life-time of an individual not inherited.

Answer 2

Experiences of an individual during its life time are in the somatic cells of the body. That is, in non-reproductive tissues that cannot be passed to the next generation. Thus, they cannot contribute directly in evolution.

For inheritance of traits over generations and involvement in direct evolution, they must be passed to the DNA of the germ cells (reproductive tissues). The characteristics of DNA are passed to the progeny and also can play direct role in evolution.
