First understand that extremely few dinkers prove out. It's often a waste of money unless you enjoy it or see something extremely promising in the dinker (keep in mind that normals are extremely variable). Often it results in lots of hard to sell normals. To start, see if you can make it quicker, if you think it's likely in a complex with something else (because it shows the characteristics; eg. Spotnose, YB/Super Stripe) pair it with a morph in that complex. Dinkers will prove out faster if they are male because you can breed a male to multiple females. Pair the snake with a suspected complex single-gene snake. Then, breed the offspring to each other or back to a parent (multiple pairings will increase the chance of finding it if it's a low-expression inc-dom trait), you could also pair one to another suspected complex morph (likely a different complex). If the next offspring still don't show anything hopeful then you can assume the desired trait isn't genetic and it didn't prove out. If it does show something promising then keep experimenting and making combos, these combos with the morphs should look much different than the combo without.
