Need help with breeding ball pythons

[The Serpent Merchant]

Wouldn't a normal cinnamon be heterozygous while a super cinnamon is homozygous? I think the het stamp is mostly reserved for simple recessive genes(where hets aren't visual) just to keep things as simple as possible since in codominate the heterozygous and homozygous forms are visual. Which makes me wonder, would a spider be heterozygous or homozygous or something else? I have no idea how it works with dominate genes.

With dominate genes there is no visual difference between the heterozygous and homozygous animal.

The only way to tell is to breed them, a heterozygous dominate will result in 50% offspring with the dominate trait. The homozygous snake will pass on the dominate trait 100% of the time.
