Normal X Pastel

[PythonWallace]

Here is another terminology issue that IMHO might be better worded differently. You aren't out right using mutation types like co-dom and dominant as genotypes like on some ball python sites but you are close to it. In the below example it's implied that your "co-dom" and "dominant" mutation animals are heterozygous based on your results. But since the pastel mutation type is co-dominant isn't a super pastel just as much a co-dom as a regular pastel? If there is a homozygous pinstripe out there and pinstripe mutation type is dominant then wouldn't the homozygous pinstripe be just as much a dominant as the heterozygous pinstripes we've seen so far? Basically I think we should stick to using co-dom and dominant at the mutation type level and not apply it to specific genotype examples.
I've argued for using one set of inheritance rules based on genotypes that applies to each mutation type and then using the mutation type to sort out the phenotypes later.

Randy, I know exactly what you are saying, and I agree that we should be using one set of rules based on genotype and not phenotype. I think that ball python genetics can be confusing to newbies, and we can do better at standardizing the lingo.

I made this chart with the thoughts that newbies can give it a quick look and see that a pastel x normal will give you chances of 50% normals and 50% pastels. Since there is no evidence of homozygotes for the spiders and pinstripes, I wanted to keep it basic. I also agree that it's important that we start recognizing genotypes for what they are, and get rid of the "all hets look normal" way of thinking. I always try to explain co-doms as being heterozygous for a super form, while having a different phenotype than a wild type color and pattern, because that's what they are, hets. Just for the sake of providing this to newbies, while not jumping to any conclusions about homozygous dominant phenotypes, I wanted to keep it simple. Obviously when I say that a spider x spider breeding will give you 75% spiders, common sense would tell you that statistically 1/3 of those should technically be homozygous animals, I wanted to stick to a simple chart keeping with what we know to be true as this point. Once people start getting into those double co-dom het recessive X visual recessive, they would be wise to dig a little deeper into genotypes before assuming any potential outcomes.

Edit: I just realized I didn't write anything for homozygous co-doms in my first post, though. That's not helping anything.
