I'm a little confused about what you are asking, so I'm going to take a stab in the dark...
There are several ways you can make BELs. Super lessers, butters and mojaves make BELs and any combination of lesser, butter and mojave will also make BEL.
If you pair your male and female together you will get nothing but BEL but only breeding will be able to tell if the offspring are lesser/mojave or super lessers. Super lessers and lesser/mojave make clean white snakes.
