There are still a lot more breedings to be done to be sure but it's looking like there may be a group of mutant alleles (different mutations of the same gene) here. This is different than say a bumblebee where pastel and spider have been proven to be different mutations of different genes. It would be more like stripe and motley in corn snakes. This theory was taken a step further last year when someone from Taiwan using the handle of Hahaman posted the theory that maybe even the dilute gene that turns a lesser into a platy might be yet another mutant allele in this group. I had originally thought platy was some sort of recessive addition to lesser but the platy butters that RDR hatched this year seem to support Hahaman's theory.
Using W for "white gene" the notation might go something like this:
w = the normal version
Wl = the lesser version
Wp = the phantom version
Wm = the mojave version
Wb = the butter version
Wr = the Vin Russo version
wd = the dilute version to make platy – apparently normal or near normal by it’s self
Having them all variations of "w" helps to remind you that (under the Hahaman allele theory) you can't have more than two of them - one from each parent. I'm looking forward to more interesting crosses to keep testing this but so far it holds up to every breeding I know of (which isn't the same as being proven). Here are some of the genotypes for the phenotypes per this theory:
Wl w = lesser
Wl wd = platy
Wl Wp = karma - blue eyed leucistic with a bit of a back stripe
Wl Wl = clean blue eyed leucistic
wd w = normal looking platy offspring used to make more platies (could also use a platy) when combined with lesser.
Under this theory leucistic X normal could not produce normal or leucistic.
