Re: Ivory
I am pretty sure that by the true definition luecistic, an ivory technically is a leucistic.
From dictionary.com
Leucistic - 2 reference results
Leucism
Leucism is a condition characterized by reduced pigmentation in animals. Unlike albinism, it is caused by a reduction in all types of skin pigment, not just melanin.
Leucism is a general term for the phenotype resulting from defects in pigment cell differentiation and/or migration from the neural crest to skin, hair or feathers during development. This results in either the entire surface (if all pigment cells fail to develop) or patches of body surface (if only a subset are defective) having a lack of cells capable of making pigment.
Since all pigment cell-types differentiate from the same multipotent precursor cell-type, leucism can cause the reduction in all types of pigment. This is in contrast to albinism, for which leucism is often mistaken. Albinism results in the reduction of melanin production only, though the melanocyte (or melanophore) is still present. Thus in species that have other pigment cell-types, for example xanthophores, albinos are not entirely white, but instead display a pale yellow colour.
More common than a complete absence of pigment cells is localized or incomplete hypopigmentation, resulting in irregular patches of white on an animal that otherwise has normal colouring and patterning. This partial leucism is known as a "pied" or "piebald" effect; and the ratio of white to normal-coloured skin can vary considerably not only between generations, but between different offspring from the same parents, and even between members of the same litter. This is notable in horses, the urban crow and the ball python but is also found in many other species.
A further difference between albinism and leucism is in eye colour. Due to the lack of melanin production in both the retinal pigmented epithelium (RPE) and iris, albinos typically have red eyes due to the underlying blood vessels showing through. In contrast, leucistic animals have normally coloured eyes. This is because the melanocytes of the RPE are not derived from the neural crest, instead an outpouching of the neural tube generates the optic cup which, in turn, forms the retina. As these cells are from an independent developmental origin, they are typically unaffected by the genetic cause of leucism.

Re: Ivory
Todd...i did read all of your post...and my head is still spinning... lol 
Thank you tho.. 
I was thinking after I posted it... That maybe they are leucistic but called Ivory to denote who the parents are?? kinda like instead of saying spider x ghost we say honey bee... ?? just a thought...
correct me if im wrong on that..
And Dang Royal Morphz, she is a cutie... whats her name??

HaHa her name is Ivory lol as far as them being a campatible Lucy they are not, because there are many crosses using a Bel maker and YB

Re: Ivory
The differences between the 2 are sutble, but there. An ivory is generally an off-white, and has a yellow dorsal stripe. Tey also tend to gain a slight color to them as they age (as I've seen, but don't really know)
BELS (both Blue Eyed, and Black) are all white with very little pigmentation. This varies from snake to snake, but in general they are all white with ZERO pigmentation, meaning they don't "brown" or "yellow" out as they get older. Thier genetic make up prevents color producing cells from from being made.

1.0 '08 Poss. Het Albino - Norm
0.1 Proven Normal - Ragani
On the way IE when I have the money:
0.1 Albino
0.1 Spider
0.1 Mojo

Re: Ivory
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

Don't think they were saying they were compatible. Just saying if we called all white snakes an ivory or a bel (granted eye colors different but roll with me on this) then we would not know the actual genetics. I have often wanted the different BELs to have different names since they are made from different morphs but since they are compatible I guess I will let it slide lol.
