I know that physical transformations are impossible so I can guess the answer but is it possible to awaken dormant traits? What I mean is if someone was short, the majority of their family were tall implying a possibly dormant trait, and this person wasn't done growing could they artificially trigger this dormant trait in any way? Even though this would be awakening an already existing trait within them I'm guessing like changing your appearance, form, etc... it's impossible if only because it's beyond our understanding.
