Do not get me wrong, I am not saying that they are anywhere near compatible with the various morphs that make a blue eyed lucey. Initially I was posting that by definition a lucey is a snake that has an inability to produce any pigmentation of the skin in comparison to an albino that simply reduces or restricts the ability to produce melanin.
However to simply restrict the definition of lucey to morphs that are all compatible with each other is not in all honasty a fair comparison of what lucey means. You must remember that Luecistic is a "real" technical term in regards to genetics. It represents a condition that occurs in all animals not just ball pythons. The names that we have attached to the morphs that in combination produce the condition luecistic not technical terms. They are simply names that we have made up.
Butters, mojaves, lessers, and het russos all effect the same allel (location) on the DNA strand and thus produce lucies when any combination of them are present. Yellowbellies and goblins effect another allel and when put in combination also produce a white snake (another form of a luecistic snake). But when one gene from group 1 (butters, lessers, etc..) is combined with one gene from group 2 )yellowbellies, goblins) you would not get a white snake since they effect two different locations on the dna strand.
I know this is long and technical and if you need me to i can try my best to explain any questions about my thoughts on this. Todd
