VPI is an axanthic line.
TSK is an axanthic line.
Jolliff is an axanthic line.

(All of these lines are named after the breeders that founded them.. VPI is a breeder!)

If you want an Axanthic Mojave, all you'd need to do is to get an axanthic and a Mojave het Axanthic of the same line. (TSK, VPI or Jolliff)

Grow'm up, breed them together, and hope to god you hit the odds!
