Yes, it's entirely possible.
When gametes (sex cells with half of a parent's genetic information) are produced, a process called 'genetic recombination' occurs where homologous chromosomes randomly swap sections of genetic information. They do this by 'cutting' their genome at a specified location and swapping their chopped-off sections with each other. This is repeated several times. This means that the final product of meiosis, an egg or sperm cell, will have a random assortment of the parent's genetic information, meaning there are essentially limitless unique sets of genes that could be carried by a given egg or sperm.
Any two given heritable traits may be 'linked' to some degree based on how far apart they are physically located on the genome. Because the location where the homologous chromosomes 'cut and paste' their genetic code is essentially random, it's less likely that two genes located close together on the genome will be separated during genetic recombination. The result is that they will almost always occur together in offspring. It's apparent that whatever causes spider wobble is in very close proximity to whatever causes spider coloring, because we rarely see one without the other.
It's entirely plausible that genetic recombination CAN separate these two traits, but depending on how closely linked they are, it may be very highly unlikely. It can't even be said with any degree of certainty that they're caused by separate genes. Either way, the fact that your lesser has the wobble is very interesting, to say the least!
Edit: If it's got defects from a known incubation issue, odds are overwhelmingly high that it's an extension of that defect. Still, it's not impossible that it's the spider's influence. Which I think would be really cool, haha.
