The Genetics Home Reference glossary defines "wild type allele" as "The normal, as opposed to the mutant, gene or allele" (http://ghr.nlm.nih.gov/glossary=wildtypeallele). So "normal" and "wild type" are synonyms. Besides, "normal" is quicker to type.
In the above definition for "super", the two genes in a gene pair could be either the same or different. For example, the type A human blood type gene and the type B human blood type gene are expressed concurrently in people with the AB blood type.
IMO, a super has two copies of a codominant mutant gene in the gene pair. The mojave mutant gene is codominant to the normal gene because the three possible genotypes (2 mojave genes, 2 normal genes, and a mojave gene paired with a normal gene) produce different appearances (AKA phenotypes). A mojave morph snake has a mojave gene paired with a normal gene. A super mojave morph snake is a blue-eyed leucistic and has a gene pair made up of 2 mojave genes.
