This is a simple genetic question, with a simple test breeding to answer this basic question about Palmetto.
Who has done to breeding to answer this question?
Where is the proof?
It is very easy to say that the "tan" offspring from Palmettos' is the result of a co-dominant gene, but breeding a Palmetto x any Corn and producing "tan" offspring is no proof at all.
It is also proof of a hybrid. Or hybrid marker with a Yellow Jacket gene expressed.
Who has bred Het Palmetto x Normal, or any other morph?
Who has bred Het Palmetto x Het Palmetto?
Photos of results would be SWEET!

Will Het Palmetto x Het Palmetto breedings prove if the Palmetto gene is visible as het?
What about Het Palmetto x Any Corn Snake?
There may be other factors to consider. How did a recessive gene such as Palmetto with "No visible Hybrid Markers", become a co-dominant gene that is visible as het all of these years later? This sounds like Boa and Python Genetics.
If Palmetto was a Yellow Rat Snake, instead of a Corn Snake and you bred it to a Corn Snake, it would produce Het Borderless Yellow Jacket offspring, het for Palmetto, just like all of the photos of het Palmettos you have seen.
The Borderless gene and Yellow Jacket Gene I have seen in our Corns is a dominant gene. They are both actually co-dominant, because they can easily be seen as het, but stand out when homozygous.
If you bred a Yellow Rat Snake x Okeetee you will produce the same phenotype as het Palmettos, because they are het for YJ and Borderless. If you raised up the females from this cross and bred them back to the Yellow Rat Snake, you will produce many Homo YJ Borderless offspring. The entire line is now homozygous for two dominant genes, borrowed from the Yellow Rat Snake.
How many times have you seen a Borderless Corn listed as a Normal? When did Borderless first come on the scene? Amel, Anery, Hypo Boarder-less, Boarder-less has been a Normal Phenotype in our Corns for a very long time. Hypo Okeetees exist, so Hypo does not remove the border from Corns, it is another gene, called Boarder-less.
If Palmetto is a Corn Snake and you bred it to a Het or Homo YJ Boarderless Corn, you would also produce the current phenotype of Het Palmettos. So which is it?
Possible test that could prove this out without DNA Tess are:
Original Palmetto x Okeetee
Original Palmetto x Yellow Rat Snake.
I personally believe the Border-less Gene and Yellow Jacket Genes are Rat Snake Genes, and like a Yellow Jacket, they can come back to bite you, when claiming that "No Hybrid Markers" exist in a line.
