I have no Problem with an good discussion! I do my best, for explaine and express my thoughts and mark them with numbers for an better answer. It is also Not my intention to be condescending or disrespectful.
Here we go:
1. “Nominat” is an latin word in the Biologie(Taxonomie). It mean the first animal of an species, that was used to describe the species. Today it also mean the "wild/normal-type" without an mutation.
2. I realized, that we all think the same about the defination of "Hypo" . As well, we all agree, that currently all or most of the Hypos are a kind of Albinos. What about the Toffeebellys? Later!
3. The genetic behind line-breeding is called "intermedier". When you will hold or increase an intermedier trait, you has to breed a pair with the same expression of that trait. When you breed an normal to an intermedier trait, this trait will be less to see in the offspring. Nearly in the middle between the origin trait and the wild-typ.
This you can see at the Hypo and SuperHypo Leopardgeckos for example.
OK and now the real hard stuff:
at first, all my knowlege about albinism and the melanin(tyrosin)-syntesis came from the human genetic.
4. There exist two diferent cycles, who has an influence on the black pigmentation. One cycle influence the amount of melanin (Hypo/Hyper) and the other cycle is the melanin-synthesis (Albino). Thats the reason, why I say: Hypo should influence the amount of black and not the melanin-syntese.
5. every type of genetic defect that has an influence in the melanin-synthesis-cycle is called Albinism. and so also Piebald.
6. everytime, when tyrosin is present but the body can not build up (spelling?) melanin(so that an Pre-Melanin is present) it is a kind of Tyrosin positiv Albinism. It makes an purple eye-background(Retina, shown through the pupil) and replace the black parts with purple or lavender colors.
7. In my understanding (and also from Raimo and other guys around me) did paradox mean: that not the animal is paradox but there is something on or at this animal, that should not or could not be there. like black spots on albinos. And we all agree, an Albino with black spots is an Albino. Right?
8. I think we both agree (like Cazey thought), that the so called Lazik-Hypo is a kind of Albinism and not an Hypo. Therefor he can not have a black tongue, because he is not able to produce melanin.
9. Banana is the name of an BP-mutation, that makes a kind of Albino with black spots.
In the end we came to the Toffeebellys.
In my opinion a name should be a name and not a description. For example: my name is Stefan and not "big European male with black hairs". Toffeebelly is our name for a Mutation, that pops out for the first time in our breeding-stock. No matter what kind of mutation it realy is.
This mutation has all traits of an Tyrosin positiv-Albinism plus black spots (like it is in Banana BPs).
The resume is, that we agree that they has to be a kind of T plus Albinism. Right?
We also agree, that black spots on an Albino are paradox-spots, because they should not be there. Right?
Thats the reason, why the Toffeebellys are Tyrosin positiv Albinos with paradox spots.
Yes, all Toffeebellys have these spots. Sometimes only some spots on the iris. or only one spot on the belly ( ask Joseph).
more under the pic.
We had many het x het and homo x het breedings and everytime the same result: black spots in different quantitys. Thats the reason why I think (very strong), that this is part of this mutation. Because: when this is a mutation by itself, we would have min 1 clutch where min 25% of the hatchlings did not have these spots. But it is not so.
I hope this helps and did not confuse to much.
I have no problem, when someone prove me wrong, because I´m alway interested in learning something new.
