The Hypo mutation is dominant. The heterozygous and homozygous forms have the same phenotype.

If there was a distinct phenotype for the super (homozygous) as opposed to the heterozygous (non-super) form, then the mutation could be classified as co-dominant.

Based on the characteristics of the mutation, and how it works, it is best to classify Hypos as incomplete dominant. Incomplete Dominance IS NOT the same as co-dominant.

Motleys are perhaps the best example of a co-dominant mutation in boas.
