Champagne x Ghost x Spider

[Slicercrush]

The way we refer to co-dom, dom and such is just how the single mutant gene looks in heterozygous and homozygous forms. Other genes have no baring on it. It being allelic proves that there is zero reason for the super spider not to exist, as the locus doesn't have any issues.
If you can make super blackheads, you can make super spiders, and ignoring all other evidence, we can still ask what's the logical conclusion based of this alone. It's lethal.

Along with the fact that most neuro issue morphs (such as woma, for example) when bred together can have really terrible side effects, it really isn't surprising. Look at pearls (Woma x Woma) which is lethal as well, though I do remember seeing something along the lines of one living, atleast for a little while, using Hidden Gene Womas bred by NERD, but I would consider that a completely different case.

I just picked up a Super Pastel HGW, so now I have 2 of the "wobble" gene snakes, staying away from breeding them together, but going to try for Pastel Soul Suckers.

I wish we had more information on the genome of ball pythons, because this would expand our understanding of the morphs/mutations we encounter to see where everyone lies and to see which are actually co-dom, dom, or recessive. In my opinion, a recessive with het markers is more co-dom than recessive if they are proven markers that are reproducible.

Would be interesting, in the least, to see what would happen with the pair. I think WorldOfBallPythons.com has some HGW x Spider snakes already listed, so my guess is that it at least isn't considered 100% lethal, though I haven't dived on the subject too much. I would guess that the Wobble would probably escalate quite a bit in that scenario, though, but I could be wrong.

Not planning on breeding them together to avoid the risk, but I too have seen HGWxSpider combos listed there, not many but a few. Plus both of those pattern reductions don't necessarily amplify each other.

I feel the same.

Wouldn’t spider HAVE to be a co-dominant trait? Since it was proven allelic to blackhead? Would that be possible if the spider gene is dominant?

I am with OWAL.

The spider gene is codominant to the corresponding normal gene. That would be fine if the spider locus had only those two alleles. Things get much more complicated when a locus has three or more alleles, as seems the case with the spider locus.

Dominant/codominant/recessive describes the relationship between two alleles. Repeat, two alleles. If only one allele is specified, then the assumption is that the second allele is the normal allele. Changing one of the genes can change the relationship. A gene can be dominant to one allele, codominant to a second, and recessive to a third.

Spider could be dominant, codominant, or recessive to another allele. If spider was dominant to another allele, the heterozygous form would die. Like spider/champagne. It has already been established that the spider gene is codominant to the normal gene. Or spider could be recessive to one of its alleles. I don't know enough about those other alleles to identify a likely candidate. But there are plenty of recessive lethal genes known in various species.
