Of course, that’s assumed given the context. Take a plant that has developed unique acclimations to a specific environment, it’s going to change when exposed to and reproduced in a different environment. I’ve watched squat indicas change after a few years of successive line breeding into awkwardly stretched and larfy trees here in SoCal. But we’re talking about “preservation” in the context of antisocial weirdos with a tent in their closet or basement, trying to share rare seeds with other internet weirdos, not PHDs in a lab
