i heard a vendor at one of the shows claim this to be true. is that correct?

If youre asking if a yellow belly to a het Ivory equals a homozygous morph, then yes that is true because a het ivory is a yellow belly. If youre asking if a YB to a simple recessive het equals a homozygous then--not likely.

Youll find that in this market people coin names for all the co-dominant "hets". You wont see that with the simple recessive stuff because a simple recessive trait [typicaly] does not express itself in the heterozygous form. Although, there are the occasional "markers" for some simple recessive hets that some people put faith in (not discrediting).
But since all simple recessive hets (knock on wood) look normal there is no reason to distinguish them by a separate name.

But because the co dom mutations are visibly different at birth (despite not being the fully expressed mutation) it helps to give a specific name to a co dom het because the co doms when breed to other co doms make some neat combinations even by themselves.

For example, if I was to state the combination between a yellow belly and a pastel I could say: "yellow belly pastel" or "het ivory pastel" or vice-versa for either.

They are both politicaly correct but the first choice seems to claim a universal preferance from the crowd. You can call your hets whatever you please. It doesnt matter so long as the person youre communicating to understands what youre talking about.

the claim was that a yellowbelly is a "gene enhancer" and that if you breed it to a het albino you get albino's, to a het pied you get pieds,etc.
i'm no expert but i certainly have serious doubts about that claim.

Some designer mutations have been created with one half of the mutation being het ivory(one allele),and the other being say, "granite"(Ebony ball)or whatever gene it is that makes the Superstripe.

ok so i assume you mean a genetic granite, but is it a universal het? can you get albino's, pieds, clowns, etc from a yellowbelly male to a female that carries the recessive genes?

No,it isn't the same gene... That's the equivalent to breeding a pair of pieds and hatching a het-ivory(It doesn't work this way.).Breed albino to albino,or het albinos to get albinos.

thats what i thought but this guy swears to it. he said if i didn't believe him that i should ask kevin(nerd),ian g,ralph davis,etc. i don't believe it, i never believed it. its guys like that, that hurt the business!!!!
