Whats the real difference between a Mojave & lesser

[JLC]

so the lesser is a super form of mojave or a different morph alltogether?

Completely different morphs. They're both "base morphs" and one does not make the other. They may be closely related, as the super form of both creates white snakes, and (as I understand it) you can also get a white snake by breeding a mojave and lesser together.....but they do have differences that are easily seen by those who know what they are looking for.
