To all writers especially those in Hollywood. Please stop using the word "clone" to describe identical copies of living things. Cloning doesn't work that way. There is a well written article about this here. http://science.howstuffworks.com/life/genetic/clone-id... Do not fret. You can still make science fiction stories about mass produced identical people or whatever it is you write. Please just use the term "duplicate" instead of "clone". To the audience it will mean the same thing, but you won't be misinforming them.
