Pictures of mom and her babies from both seasons if possible. But yes, it seems as though some traits can be passed on regularly. I'm not sure exactly when it goes from being "dinker" to genetic. Maybe if mom or dad has the trait, offspring have it, and maybe grand-offspring do as well ? That looks silly doesn't it? What i mean is if Sookie has the look, her pastel son has it, and then later when you breed him to a different snake his offspring have it to. Maybe then it's considered genetic?
