We know that spiders tend to wobble. Does the spider gene also make a spider embryo less fit to survive to hatching, compared to a normal?

Probability theory says to expect 100 normals and 100 spiders out of 200 eggs from spider x normal matings. What if there are 80 spiders and 120 normals? Or 120 spiders and 80 normals? Or some other difference from expected? A Chi-square statistical test will tell whether the difference seems to mean something.

If the number of spider hatchlings is significantly less than the number of normals, it would support the belief that a ball python with a pair of spider genes is likely to die before hatching.
