Why are traits acquired during the life-time of an individual not inherited?

Solution 1

This happens because an acquired trait involves change in non-reproductive tissues which cannot be passed on to germ cells or the progeny. Therefore, these traits cannot be inherited.

Solution 2

Traits acquired during the lifetime of an individual are not inherited, as these traits develop in the individual in response to the environment. Only those traits  which are associated with the DNA of the parents are passed onto children. Acquired traits do not make any changes in the DNA; hence, they are not passed from parents to children.
