Two of those theories are found in genetics.

First, the Spider gene could be fatal when homozygous. Normally we assume the Spiders we see are heterozygous (Ss), so the snakes only have one copy of the Spider gene. Two Spiders bred together would theoretically produce some eggs that die in incubation when they receive two copies of the gene. IE, are homozygous (SS).

Second, the Spider gene could simply be dominant. Therefore, heterozygous and homozygous Spiders would look the same. Once and a while someone may come across a Spider the produces all babies with at least one copy of the Spider gene (depending on what it was bred to).

No one, to my knowledge, has sat down to analyze their hatch records for Spider to Spider pairings that result in fewer than the expected number eggs, which would support the First theory. Nor has anyone checked to see if they have a Spider that produces only babies with the Spider gene, supporting the Second theory.

I would say your Honey Bee X Spider het Ghost pairing should be fine. Either you will have a few less eggs hatch than you would expect, or you will have all at least Spiders in your clutch (if you have a homozygous Spider). So go for it!
