It is as the others have stated, 25% chance per egg for a BEL. However, I for one do not mind the "dirty" look of the mojo x mojo BEL. If I want an all white snake, I'll wait for my pastel ybs to mature and try my luck with an ivory, or if I'm lucky, a super pastel ivory. Mojos can also be bred with pins to produce jigsaws, pastels to get pastaves, cinnamons to get savannahs and spiders to get mojave spiders to name a few. Up to you in the end, but plenty of possibilities!
