Mojave spider female to butter male?

[Lthv]

It's an 12.5% for any of the outcomea

12.5% Lesser Mojave Spider
12.5% Lesser Mojave

Those two animals should look the same, the BEL visually overpowers the effects of the spider, so if the goal is to produce a blue eyed leucistic animal you would still have a 25% chance to produce one, which is the same as a Lesser x Mojave pairing. Only difference is the BEL would have a 50% chance of carrying the spider gene in addition to being a BEL. If you did hatch a spider BEL you may see some head wobble or typical spider behavior, but your animal should still be what you are trying to hatch from a visual standpoint.
