>blue eyed lucys (which are effectively then het for two different traits).
I get the feeling from this that you are thinking that there are two gene pairs involved. A blue-eyed lucy from a mojave X lesser cross has two gene pairs that contain mutant genes. One gene pair contains a mojave mutant gene and a normal gene, and the second gene pair contains a lesser mutant gene and a normal gene.
The way we think it works, there is only one gene pair involved. A blue-eyed lucy from a mojave X lesser cross has a mojave mutant gene and a lesser mutant gene in one gene pair.
>with one allele from a mojave, and one from a plat, is there just no genetic information to give it normal colors?
That's the general idea. The two mutant genes in one gene pair block the biochemical pathway that produces normal colors. When there is one normal gene in the gene pair, the block is only partial.
