I think the non genotype terminology is very confusing.

What does “super” mean? I'm thinking “visibly different looking homozygous of a co-dominant mutation” but I'm not sure. If it's more general and is the same as “homozygous” then a dominant mutation could have a super too, it would just look the same as the hets for that dominant mutation. I prefer to use “homozygous” which has a more established meaning - having matching versions of the gene in question.

And what about “dom X dom”? Dominant refers to the mutation type, not a specific animal. I think the example was meant to indicate het X het for a mutation that happened to be the dominant type. But if we just call it het X het then it's easy to remember the same genotype inheritance rule that applies regardless of mutation type and was probably learned back with albino hets:

het X het = 25% chance homozygous mutant, 50% chance heterozygous, 25% chance homozygous normal.

It's just that once you apply the dominant mutation type to these results you see that the 25% homozygous mutant look like the 50% heterozygous so comprise 75% of the clutch looking the same. In this case you could refer to them as a group of 33% chance possible homozygous or even 66% chance possible hets I suppose. It will take some getting used to if we do eventually prove a dominant mutation.
