Yeah like everyone else is saying, Mojave's will make lucy's but they are usually "dirty" Lucy's.. Not as white as you can make.. Plus the eyes are not quite as bright blue. Which is why im getting a BEL from a Russo Het x Lesser combo & a Butter female. Putting these 2 together (depending on clutch size) i have good odds of getting clean white BEL's, Butters, Russo's, & Lesser's. It will be an exciting clutch since the anticipation of whats in those eggs will kill me!
Try to stay away from Mojave if you really want a clean pure white snake. But they do make other nice combos like Mojave Pastels (Pastave) Mojave Lessers etc..
