Here is an exact quote from the UK reptiles forum:

"Super salmon (= homozygous salmon) x super salmon produces all super salmon.

Salmon (heterozygous salmon) x salmon produces
1/4 homozygous salmon (pair of salmon genes) (= super salmon)
2/4 heterozygous salmon (a salmon mutant gene and a normal gene)
1/4 normal (pair of normal genes)

All salmons are hypos, but not all hypos are salmons. You have to be a bit careful when buying. For example, orangetail is a hypo, but it is a different line from the one that Rich Ihle established. It is not clear whether the mutant in the orangetail line is the salmon mutant gene or not. As far as I know, nobody has done the necessary testing, which is a bit more complicated than just mating an orangetail to a salmon. Then there is the Sharon Moore caramel hypo, which is a recessive mutant that is probably unrelated to salmon. Another problem that would be nice to test."
