There is no such thing as a het Tessera that is not a visual Tessera. Correct? I don't know why I said the above example with the Amel- I guess because I can't get used to the "super" concept!
Yep. If there is a "regular" form and a "super" form then all the "regulars" are the hets and in this inheritance mode all hets happen to be visuals. Homozygous individuals will be visuals too.
Now, the difference between co-dom and dominant genes is the fact of whether you can see a difference in the two forms.
If the het form and super form are the same, people usually refer to it as dominant and only breeding trials can tell the difference. Spider ball pythons are an example of such a gene...but there are few people who have taken the breeding trials this far as most people take their spider to something else and rarely is a spider X spider cross done as there as been no difference in offspring...i.e. no super visual. But...it is rumored it may be out there.
If the het form is different looking than than the super it is often referred to as a co-dom. Mojave ball pythons come to mind as a super mojave is a leucistic....very different looking than a mojave.
The confusion really comes as they appear to be the same word with a prefix but they do not translate to: co-dom = het and dominant = homozygous. Very different definitions based on whether there are visual differences between the two.
Whether tessera is dominant or co-dom probably remains to be seen but it looks like that pin-stripy may be some sort of indication of possible co-dom status. :shrugs:
Also, just for technicality reasons...there is a chance (slim, I know) that the odds were REALLY crazy and instead of the offspring being 50% on AVERAGE tesseras, all of them happened to be tesseras and if so this would make no super form. It is a stretch but it could happen.
