What does the particle theory say?

Answer 1

The theory of particulate inheritance is an idea that originated with Mendelian theorists (or by Mendel himself) stating that characteristics can be passed from generation to generation through "discrete particles" (which meant genes). These particles can keep their ability to be expressed while not always appearing in descending generation. This is an old theory that while is still basically holds true, has been greatly expanded upon by geneticists later on.
