So in the Star Wars universe, Jango Fett is killed. Because he is the source of the genetic material for the clones, they would need to find a new source. However, after the clones kill off the Jedi and the Empire rises to power, there seems to be no lack of Stormtroopers, whom I am assuming are just mainly ex-Clone troopers.
Because all of the Stormtroopers are humanoid, the empire could not just be using any alien species they find. Are they using cloning still? Or are they just recruiting? And if they are cloning, whose genetic material are they using?
