A super pastel has two copies of the pastel mutant gene in the gene pair and is significantly lighter in color than a pastel.
A super usually has two copies of a codominant mutant gene in the gene pair. A super may have two copies of a dominant mutant gene, but dominant mutants seem to be a lot rarer than codominant mutant genes, at least in ball pythons. A super never has two copies of either a recessive mutant gene, like albino or pied, or a normal gene.
