Salmon (AKA hypo) is better called a dominant mutant gene than a codominant mutant gene.



A het for hypo has a salmon mutant gene paired with a normal gene. Just as a het for albino has an albino mutant gene paired with a normal gene. The appearance (phenotype) of the het is what determines whether a mutant gene is considered dominant, codominant, or recessive to the normal version of the gene. There is a chart showing the differences at the bottom of the page linked below.



The het salmons and the homozygous salmons are variable enough that the only way to be certain what you have is by breeding test.



"Super" is herper slang for a snake that is homozygous for (has two identical copies of) a dominant or codominant mutant gene. As far as I know, super or super salmon is about all there is for a different name. And most of the time the ads say something like possible super.



You might want to look at Rich Ihle's http://www.salmonboa.com. He originated the line. He does call salmon a codominant mutant gene. I do not agree with that because too many breeders on this forum have said that the homozygous and heterozygous salmons overlap in appearance.
