Throughout genetic history, there have been many concepts of heredity, both incorrect and correct. Scientists once believed that genetic information would travel from various parts of the body and then collect in the reproductive organs of the human. Another bizarre concept is the idea that a miniature organism live in sex cells throughout life and that all the traits are inherited from one parent when an offspring is born. Lastly, the idea that genes in the body mix together to form into the genetics material is false. The correct concepts include the germ-plasm theory where all cells have a complete set of genetic material. The cell theory of all cells arising from only cells is also proven to be true concept of heredity.
