The tricky part comes though when what the trade considers two different mutations happen to be alleles (different mutations of the same gene).
A Karma is the combination of phantom and lesser which it turns out are part of a large blue eyed leucistic allele complex. A Karma bred to a normal is sort of like a super breeding in that none of the babies are normal looking (each egg has 50/50 chance of being lesser or phantom, but no normals and no Karma). Also you can't have more than two copies of the same gene so it's not possible to make a lesser phantom mojave since those mutations are alleles. There is a different allele group around ivory/super stripe and probably another one around the black eyed leucistic.
