Codominant traits are described in the science of genetics, which is not a exact science. A example of codominance is the trait of hypomelanism. As when you cross a hypo to a normal you will get 50% hypomelanistic hets and the others will be normals. So we do see it outside of just the hobby. Also it is not inaccurate.

Co dominance is a genetic term but it is defined as two genes that are both expressed in the offspring. Meaning the offspring have qualities from both parents but do not look the same as either parent. Hence why it is inaccurate as a banana always looks like a banana, not a mix between a normal and a banana. Incomplete dominance is when the dominant allele is only partially expressed in heterozygous form and fully expressed in homozygous form, i.e. the super form. In ball pythons hypo is a recessive gene and not dominant in anyway. I would urge you to do some research on genetics outside of the reptile world.

[Albert Clark]

Your basically not comprehending.....hypomelanism is codominant. I used hypo in its short form for hypomelanism. Please keep your urgings to yourself, thank you.

[RAD House]

I am not understanding because you are not explaining your view well. Hypomelanism, as in Albinism? Albino in ball pythons is also recessive and humans as well I believe. Hypomelanism in what species is codominant? What form of hypomelanism are you referring to? Albanism, luecistic, hypo/ghost? You often seem to struggle with genetics so I offered some good advice. If you can't take a friendly suggestion, all I can say is the internet is no place for you.

This is getting off topic. Thanks for your help in the Champagne morph. Friendly? Haha. Take care.

...I thought hypo was recessive (but I don't know when it comes to balls) and if that were the case, in the pairing mentioned, all offspring would be 100% het. You don't have hets when it comes to incomplete/co-dominant traits...to truly be a het the trait is carried but not expressed. Those cases where "het" is used in regards to anything that isn't recessive is definitely not scientific but hobbyist nomenclature as far as I know.

Male's
alleles:
H' H
Female's
alleles: H H'H HH
H H'H HH
Figure 1: a male Hypomelanistic Boa Constrictor is crossed with a normal female.
A well-known example of co-dominance is the trait of hypomelanism in the Colombian Boa Constrictor. In the Punnett Square at left (Fig. 1) we cross a male 'Hypo' to a normal female.

Statistically, this cross will produce 50% hypomelanistic specimens. As always, each of the resulting offspring received one allele from each parent. Thus half are heterozygous for hypomelanism (Hypomelanistic, H'H), and half of the offspring are normal (HH). Excerpted from a study guide of mine.

Hypomelanism in boa constrictors is actually an incomplete dominant trait, Albert. No such thing as het hypo in boas. In regards to most other species, including ball pythons as far asnI am aware, hypo in those cases would be recessive.

Thanks Andy. NP. I appreciate your courtesy.
