3. Dominance
A dominant trait is just that, dominant. The spider morph of Royal python is a good example here.
Breeding an animal displaying the dominant trait (a spider Royal) to a wild-type animal will produce 50% spiders and 50% normal siblings, just as with an inco-dom trait, but.......breed 2 spiders together and all you get are more spiders!! There is no super form. Initially this trait was believed to be inco-dom due to the ratios obtained when a spider was bred to a normal Royal, but when spider x spider breedings were conducted only more spiders were produced, i.e. no 'super' form.
