If you bred an BEL (lesser x lesser) with an axanthic pied, you would only get lesser 100% double het axanthic and peid.
In order to get a BEL Axanthic pied, youd would have to have two BELs axanthic pied, or boh of them that are double het for axanthic and pied. Because we are talking about a BEL, you would still most likely end up with a completely white snake and would not be able to tell if the BEL has axanthic or pied in it.
