Nah--I think it just says that the daddy gene is a BEL allele, and we should expect to see mojave daddies, mocha daddies and phantom daddies in the near future.

I think the only way to conclusively prove butters != lessers is to actually sequence a bunch of ball python genomes, isolate the BEL complex, and find out whether butters and lessers are carrying an identical gene in that location.
