I think I know where you were going with this... and in the wild I would say that every ball (that looks normal, that is) has an ever-so-slight chance of carrying something unique. Who knows who its grandparents were, right?

In captivity, with so many breeders out there, your chances are next to none for being 'het for something.' Is it possible? Perhaps, but if it was captive bred then whoever bred it knew its genetics.

Great place for an uber-experienced breeder to chime in- has anyone ever thrown a morph from supposedly normal parents?

Along genetic lines, I wonder if anyone has purposely bred large or long normals, sort of the opposite of the dwarf retics they are breeding... I would love to have a ball that got 7-8 feet, or one that got fat like a burm... I don't know if it's even possible, but it would be cool. I also wonder if there would be any genetic defects with them.
