Great question Jorge, some of them are so light and some are so dark that they look like different morphs. The reason that I know they are all Jellies is because of what the parents were.
All but a few came from either Jelly x T Negative (Yields Jellies and T negs) or PB x T Negative (Yields all Jellies). The thing that I played with this year is deciding which Jellies, T Negs, and PBs to pair up with which in order to get the most contrast. The insanely dark ones that I posted come from the Swampland line which seems to also throw PBs, yet the PBs from those breedings are very obviously PBs and much lighter than these Jellies.
Another thing to consider if you are breeding Jelly x Jelly for example (because it will yield PBs as well as T Negs and Jellies) is which of the questionable ones are males and which are females. Jelly males are for the most part much brighter, lighter, and easily distinguishable (especially after a few sheds). Jelly females tend to be very dark and stay that way. Having seen a fair amount of both PBs and Jellies in my own collection as well as in others (and pictures), it seems to have helped me pick up on the little things that separate them and is starting to make me feel more like a Ball Python guy haha!
The head pattern is also helps me determine one from the other if I am in doubt. And if I really can't decide (happened with one animal so far this year).... I will just keep it and breed it to something that will prove it out one way or another.
