You pretty much have it. A Dominant trait will look the same whether the animal is Homozygous (HH) or Heterozygous (Hh). A Homozygous dominant bred to a normal will produce all Heterozygous babies of that phenotype. For example, the morph Champagne is *supposed* to be dominant. So a Homo Champagne bred to a Normal will produce all Champagnes, but they will be Heterozygous for that trait.

I think people mostly consider Spiders to be Codominant, but there is very little statistical or anecdotal evidence either way. I have never heard of anyone breeding a Spider to a Normal and producing all Spiders *every single time* which would essentially prove the animal to be a Homozygous dominant (or just extremely lucky).
