Because only the germ cells are passed on to your offspring (ie your eggs / sperm), mutations that arise in non-germ cells (somatic cells) will not be passed on.

Sex (germ) cells are separate and distinct from any organism's body cells. In the case of females, the egg cells are pretty much already determined at birth. In the case of males, the germ cells (which produce sperm cells) live in actual and total isolation from the rest of the body. The one time when something can be passed on is radiation that effects the germ cells the same way it effects the rest of the body.

because mutation only happen if they is mutation agent like alkylating agent.. and if the agent affecting the maternal, so only mom will get it.. and most cases of mutation is not inherited...
