But because Banana and Spider are co-dominant genes, the offspring could be banana, spider, normal, or banana-spider. There's no way to know for certain until the eggs hatch, basically. You could end up with all banana-spiders if you get really lucky - or you could end up with all normals, if you're really unlucky. Both of those are possible outcomes, but pretty unlikely. Most likely, you would get a mixture of offspring. It's a random shot, and there's really no way to control it. Even if you had two Bananas and bred them together, there's the possibility of normals. I think the only way to guarantee that the offspring will have a co-dominant gene in them is to have a parent with the super form of the gene, so that you know the offspring will get a copy of it - for example, if you had a Super Banana, you'd be assured that all the hatchlings would, at the least, be Banana.

There are others around who know far more about breeding snakes than I do - hopefully they'll chime in if I've got anything wrong, and correct me!

Actually a spider is a dominant gene trait not a co-dominant.
