I know... Didn't know what it was till yesterday. That's whats cool - I learn something new every time I come here. LOVE IT!!!

I would love to have a luecistic (SPELLING?) - then I saw how much they go for :O. They are BEAUTIFUL!!!!

you just need a couple of mojaves to make your own ;)
They are really beautiful!

If you're really interested on learning about these animals you should consider buying the book from VPI or NERD. They're a little pricey for a book but the amount of information contained inside is priceless. (Not to mention all the great pics :))

Why does this definition keep getting posted over and over when it's been shown not to be true an equal number of times?

Heterozygous means you carry one normal and one active allele for a particular gene. Dominant and Co-dominant genes both produce visible mutations in their heterozygous form.

Correct but they still only carry one copy of a gene needed to make a visual mutation different than the base gene..

Yes, "one copy of", and not "half required to produce".

The difference is one of "a pastel is a het" vs. "there are no het pastels". The second statement is a widely held belief, even though the first is the accurate statement, simply because people are led to believe that "het" equals "looks normal".

CtrlFreq Am I following this right...

What you're saying is any co-dom trait is het for the super form?

So we could if we wanted to call regular pastels "Het for Super Pastel"?

It's always a word game isn't it we try and keep it simple for beginers to undrstand..I said.

Which is true last time I checked all super forms of co-dom animals are visual mutations. And since it takes 2 copys of the genetic code to produce if an animal only has one copy then by my math that that animal has HALF the genetic code needed to create a visual mutation. If it took three the animal would carry 1/3rd. So you can't make a super codom or visual recessive with out both HALVES or COPYS of the genetic code. The difference is that the het form of any co-dom is visualy expressed where as recessives are repressed visualy in there het form by the wild type genes.

So in truth Pastels are Het Super pastels, YB's are Het Ivories, Het Reds, Het Russos', all are visual co-dominate mutation that carry one half of the genetic code needed to produce a visual mutation.

Holy crap people

Recessive= 2 copies of the same allele needed to create the phenotype (expression). 1 copy is called a "het" and appears normal.

Co-Domiant= Partially expressed phenotype when only one allele present. Full expression when both copies are present. (pastel as an example is only partially expressed, and a super is the full expression of the pastel gene)

Dominant= Fully expressed when only one allele present. (dont matter if it has one or 2 copies, it's fully expressed)

But yellowbellies are often called het ivories
maybe it's just because it's a (MUCH) less obvious mutation than the other het co-doms
