        Self fertilized plants do not produce more members of the same
clone because the chromosomes in cells get scrambled by processes such
as "cross-over" .  The genetic cells thus receive one half of a
scrambled set which will be different for different genetic cells since
the cells which produced them were scrambled differently.
        Imagine two identical decks of cards. Shuffle each and take out
half of each deck.  The two half decks will not have identical cards.
With chromosomes it's not quite that simple but analogous.
