Question about B.E.L.S

I was wondering if I had a clutch of a Mojave x lesser and got some blue eyed Lucy's. if I put two lesser/Mojave bels together I will get all blue eyed Lucy's right
25% lesser
25% mojave
50% lesser/Mojave
Correct?

Yes. Pairing your two Lesser/Mojave BELs together would give you all BELs. You would end up with 25% Super Mojave BELs, 50% Lesser/Mojave BELs, and 25% Super Lesser BELs.
