>>511321881i think its less "changing" and more "deleting", or more likely, preventing it from forming in the first place. its preventative tech
downies come from an extra mutated chromosome. deleting an extra one that doesnt actually need to be there in the first place is definitely much much easier than changing one chromosome into an entirely different one. and its not even clear what that would even do, changing a Y to an X
it would probably result in the body freaking out and attacking itself, and it certainly wouldnt turn you into a woman magically. it would only make you, chromosomally, into a bitch. youd still just be some bald fat faggot wiht bitch tits
