No, you wouldn't. Mojave and lesser are two different morphs, but when the genes are together in the same snake, they act together in a similar way to a snake that has 2 lesser genes or 2 mojave genes.

Say you paired a Mojave x Lesser,
in theory the odds would be like this:
1/4 babies normal
1/4 babies Mojave
1/4 babies Lesser
1/4 babies BEL

Now you take that BEL and you pair it to a normal, you'd get:
1/2 babies Lesser
1/2 babies Mojave

Mojave x Lesser makes a similar looking snake to Lesser x Lesser, but it still contains the two different morphs.
