Question: who are clone troopers clones of?
Answer: Clone troopers were grown on the planet Kamino from the genetic template of bounty hunter Jango Fett, and made into a highly-efficient military force. The origin of their creation was murky; Prime Minister Lama Su told Obi-Wan Kenobi that the order was placed by Jedi Master Sifo-Dyas in the name of the Republic.
