Such traits are called acquired traits. Acquired traits are experienced by an individual during his lifetime. These traits involve changes in non-reproductive cells (somatic cells) which are not transferred to germ cells. So, these traits cannot be passed on to the next generation.
For example- Learning skills like swimming, dancing, cooking, body building, etc are acquired traits and can not be passed on to the next generation.
