possible way to prove if butter and lesser are same or different morph?

[Watever]

Mojaves appear to have the same gene that causes leucism in the super form and white sides in one gene carriers. I think they just have other genes influencing pattern. I bet if you bred mojaves repeatedly to reduced pattern light colored normals, you could make something that looks like a lesser/butter. We've already seen pics posted here of light colored mojaves that have been confused with lessers.

I am not sure about that. But could be true that other gene are influencing the lesser or mojave look. But I doubt. Otherwise, when you breed a a Mojave/lesser lucy to a normal, you would have mojave that look like lesser and vice versa no ? Cause the ones I saw were looking quite different.

The Lesser ghost and the Mojave Ghost are totally different. Just like the Lesser Pastel is to the Pastave.

But with genetic, we never know Unless we are able to do a DNA test and identify the loci, then look at the difference between the genes, it will be hard to tell. It will be worse once more combos get created.

But if a lesser looks like a mojave, I wouldn't want it
It's like getting a bulldog that looks like a German Sheppard, we won't win any dogs competition...
