Het for something? Sure! Het for a recognized morph? maybe, maybe not. Just about every trait that we see in our snakes is genetic. Disclaimer - there are traits that are environmental, possibly caused by incubation anomalies, like ringers and other pattern/color anomalies. But, things like high gold, melanistic, black back, jungle pattern, reduced pattern.... those are all most likely genetic, just not necessarily genetically reproducible. Most of the morphs that we have were originally imported as wild caught snakes. That means that there are plenty of snakes in the wild that carry the genetics for these traits. With recessive traits, you can't tell by looking if a snake is a het. So, that CH snake that you picked up at a show/pet store could certainly be carrying the gene for ghost, piebald, clown, albino, lav albino, caramel albino.... But which one??? The only way to know would be to get extremely lucky, or breed child back to mom or dad. Of course, if mom is het for something, and you breed her son back to her and don't get anything, you may have missed the odds, or the son might not have received the gene (50% chance). In the last couple months there have been two different threads here about someone getting morphs by breeding their pet store/CH snakes. One got ghosts (hypos). Here's the thread...
First hatchling ever!

and one got PIEDS!!! Here's the thread...
WOW!!! I'm on top of the world!!

So it happens! Not to me (yet), but it happens!
