Sean, Beautiful animals and great photos. What were you thinking? I would've hung on to those! You really are a nazi getuala addict...only a goini will do 
From the percentage, I would guess that that appearance is a recessive trait, I guess whoever has them now could prove that or disprove it. What I find amusing is that when it's benificial (i.e. releasing some captive produced goini back into the areas the parents came from/or some floridana back into Paynes Prairie) everyone is up in arms about how the babies won't survive and they quote the old attempts/failures at releasing couperi as a precedent. But no one questions that someones captive raised goini/flordiana cross could be dumped into the canefields and not only survive but start reproducing with the locals.
And before anyone mentions it yes I am fully aware of the chance that pathogens could be introduced into the wild populations as was done with Gopherus, which is another, very conciensious reason to use extreme care when re-introduction is considered. I am not referring to that aspect, the survivability is what I am confused about....
With Ball pythons and Cornsnakes there are over 30 and 50 (roughly) recognized heritable traits....why is so hard to believe that kingsnakes can't exhibit the same tendency?? Regardless of the distaste many have with all these "ugly" mutations the great majority of them came from the wild. Even two apparent combos have been found in the wild! Want to try and calculate those odds??? Southwest Florida is a hotspot for wild collected mutations in cornsnsnakes, why not the canefields for floridana? With the population there it would make sense. Wouldn't a large population in a static or shrinking habitat see a great deal of sibling breedings (the necessity for recessive traits to show themselves) Just a thought that makes more sense to me than the escapee or nefarious puposefully released intergrade theory.
