Anything with the spider gene in it will have the wobbles. it can show up or go away at any time in their life. Any offspring that are spiders or a combo with spider in it will also have it. Morphs that do not include the spider genetics that are produced by a spider will not have the wobble.
Wobble really isn't anything to be worried about. it is very rare for the wobble to be anything negative to the snake. It is something to keep in mind but really most spiders don't have any issues and live ling happy lives.
