- "Ani, I'm pregnant."
- ―Padmé Amidala, to Anakin Skywalker
Reproduction was the biological process in which a new life form could be created from "parent" lifeforms. For humans, that process was the result of a sexual union between a male and a female, resulting in the female becoming pregnant and giving birth to children. Senator Padmé Amidala of Naboo became pregnant during the Clone Wars, with Jedi Knight Anakin Skywalker as the father. Her pregnancy resulted in the birth of twins, Luke Skywalker and Leia Organa. By the time of the Clone Wars, it was believed that the human women of Coruscant no longer carried or delivered their own progeny and chose to hire others to do it for them. However, during his imprisonment and subsequent questioning on Vallt, Galen Erso disputed this, suggesting it may either be a myth or simply an exclusive practice of the Coruscanti elite.
Reproduction could also be replicated via cloning, a process in which the DNA of one life form could be copied to produce genetically identical individuals. Prior to the Invasion of Naboo, the Kaminoans cloned bounty hunter Jango Fett, resulting in the eventual creation of the Grand Army of the Republic.
