Wow... you're absolutely correct. I may have missed something, but everything I read was totally right. A normal hypo has the genotype "Hh" (or whatever letter you want to use). It is therefore heterozygous and if bred to a normal snake would produce half hypos/half normals. A super hypo is HH and can therefore only pass on the hypo allele (but the babies would all be "Hh" hypos, not supers.) Hetero and Homo have nothing to do with dominant or recessive, it simply depends on the nature of the particular morph.
For example, when dealing with the HYPO morph (a dominant morph) you can get:
HH= super hypo
Hh= hypo
hh= totally normal animal (no hidden genes)
And when dealing with the ALBINO morph (a recessive morph) you can get:
AA= totally normal animal (no hidden genes)
Aa= normal-looking animal that CARRIES the albino gene
aa= albino
Therefore, the difference between dominant and recessive genes is that a Dominant "Het" displays the morph, whereas a Recessive "Het" hides it and looks normal.
As far as your explanation of dom and co-dom, the hypo and motley morphs are great examples. A motley is technically Het for the solid black super motley...Just like a Yellow Belly ball python is Het for Ivory.
It's hard to explain Punnett squares to people, I've almost given up on trying to explain them to my boyfriend. Good luck though!
