Is there a Morph you will never own/breed due to genetics?

[Blue Apple Herps]

I can't think of any that I wouldn't work with. There is the kinking issue with caramels, but I'd only buy one from a line that has been outcrossed enough where there wasn't any kinking. Plus kinking can happen to any animal, so that's not reason enough for me not to work with them.

And same thing with spiders; my spider is one of my best eaters and growers - but has a little bit of wobble. It's not so extreme where its alarming, but I think it gives her personality. I don't see any suffering and as far as I can tell it doesn't impair the animal in any way. So I will continue to work with spiders.

Since the spider morph does not have a visible super form, it could be that the severe wobblers are homozygous for spider (or maybe homozygous spider genotypes are lethal and the eggs are reabsorbed so you'd never even know), and perhaps the spider and wobble genes are closely linked (at two loci that are physically near to eachother on a given chromosome). It'd be interesting to collect data from the large scale breeders to try and figure out what's going on with these morphs that seem to associate themselves with deformities (and perhaps figure out how to avoid them).

The linked theory is interesting. If that's the case, would be nice to find one that's had a recombination event that could separate the wobble from the spider gene...
