This story takes place about 300 years in the future and humanity has since come into contact with hundreds of alien races, you get the picture. Basically, I have this character who is half human and half alien, but the issue arises in that her alien heritage was an infamous and feared race thought to have gone extinct years ago. This puts a pretty hefty bounty on her since she possesses said race's key traits. I won't get into all the details, but this begs the question of "why go to the trouble of trying to re-capture her if cloning is an option?"
Based on what we currently know about cloning (or theorize), is there some biological/genetic phenomenon that would render her unable to be successfully cloned?
