How is it splitting hairs?
A snake cannot be het for Miami or Okeetee, right?
Excessive red pigmentation works the same way as those two phases of corns.
Hypererythrism (excessive red) is not a simple recessive genetic trait - it is inherited at varying levels (each individual offspring is different).
A simple recessive gentic trait is an "all or nothing" scenario - hypererythrism is not. Therefore a snake cannot be het for it (just like a snake cannot be het for Miami or Okeetee).
A snake can be het for diffused sided, but not hypererythrism. Even if it could, the snake would be a "double het" since two genes are at play.
Selling something as a het implies that it needs to match up its recessive gene with another snake carrying that gene in order to make more of the morph. This is not the case with bloodreds. Call it "splitting hairs" if you like, but to me it's a pretty big difference.
And to the person who posted the plasma questions. No, the red is not inheritable in a simple recessive genetic sort of way. Though the snake still could very well have been the result of a bloodred combo.
