Okay, I’ve read a few threads on this subject, and I’m still a little lost about what a hidden gene is.

But here is what it seems like: A hidden gene is a different allele that rest of the same locus, but has no effect on the appearance of the snake until mixed with a certain mutation? So there is no visual way of telling if a snake has a hidden gene or not, until mixed with whatever morph “releases” the hidden gene’s appearance?
