IMO, there has to be the ability to produce a homozygous arabesque. Since the trait is at minimal known to be dominant, the only question remaining is could it be Codominant. For it to be Codominant, the homozygous or "super" form would be a third, easily distinguishable phenotype. In other words, in a het arabesque to het arabesque breeding there would be three visibly different groups of babies:

Phenotype 1 - 25% Normal - having no arabesque genes
Phenotype 2 - 50% arabesque - having 1 arabesque gene
Phenotype 3 - 25% homozygous - having 2 arabesque genes

I would think that since arabesque has been around for a while that someone would have been jumping up and down about there visibly homosygous babies by now. With the lack of that, I'd expect arabesque to fall into the dominant trait where the same het x het breeding would yield:

Phenotype 1 - 25% normal
Phenotype 2 - 75% Arabesque (1/3 homozygous)

And that the homozygous ones could only be proven by breeding. Of course, just as in salmons there could be probable ones, just nothing certain.
