With each addtional clone you buy/recieve after the original six the chance of "genetic drift" increases. Citizens above BLUE clearance can pay to have defects removed from new clones.
This brings up an interesting question:
Is every BLUE citizen that pays for this service a traitor because they know they have mutant powers and haven't told Friend Computer?
Is every BLUE citizen that DOESN'T pay for this service a traitor because they have mutant powers they aren't telling Friend Computer that they have and wish to keep?
Every GM is right but as I am a GM (though not of this campaign, I'm running a UV campaign)...
Genetic drift is different from that of mutation. Mutation means you have special powers: Teleportation, Machine Empathy, Charm, stuff that can theoretically be useful for said mutant (even if it can hilariously backfire and it's treasonous if you don't register them). Genetic drift on the other hand is utterly useless: extra fingers, spontaneous twitching, nearsightedness. Mutation is a dangerous but useful tool, drift is just utterly harmful and you should probably try to get rid of it as soon as possible before the GM takes advantage of the drift to do terrible things to you.
There is no stigma for having genetic drift (it's like having a disability, people aren't going to view you as inferior for it...at least not publicly), while there's lot of stigma for having a mutation (how dare does that man commit gene treason and have special powers while I don't!). And because genetic drift is rather obvious to any observer, there's no need to register it.
