What is the differance between a blizzard and a luecistic?
What are some of the comon morphs, even high end and what price are they going for?
 
Blizzards and leucistics/patternlesses are simply different recessive traits. The way you tell them apart is that blizzards tend to turn more white than yellow as they age whereas patternlesses stay a uniform yellow. Blizzard hatchlings are born with gray heads and have a flat, uniform white body (or yellow body with gray head and a white tail). Patternless babies are born yellow with this really cool "water ripple" pattern on their back that disappears with age.

I think it's been accepted within the leopard gecko community that blizzards are the true leucistics, whereas patternlesses are a unique recessive trait. The reason patternlesses were called leucistics at first was because they were discovered first. True leucistic animals (and this holds true for all species) have a patternless, very pale body with DARK eyes.

A good place to see the price breakdown of most gecko morphs is www.crestedgecko.com.

Soooo is a patternless the same thing as the thing that is normal called a luesisctic?

Also the term patternless is more correct as there is yet to be a luecistic leopard gecko.

I don't think I've ever heard this, luecistic animal are pure white with no trace of pigmint from the day they are hatched/born if I'm not mistaken minus thier dark blue/black eyes this doesn't stand up to what blizzards are.

yeah but leucistic snakes have scales whereas a leopard gecko just has bumpy skin. leucistic tigers aren't solid white. info on leucistic tigers

if you were to look under the scales of a leucistic cobra or hognose snake im sure you'd find that they do not have white skin.
 
In what way? I've seen plenty of leucistic animals (Canada Geese, Laughing Gulls, American Alligator, Ball Python, Red-tailed Hawks, Ring-necked Pheasants, the list goes on) and they all show the same characteristics of a blizzard leopard gecko.

Leucistic animals are NOT always pure white. Many species tend to be more of a very light chocolate color. A quick search on google (LINKY) can give you many examples of other leucistic animals.

If you think that blizzards aren't true leucistics because of their gray heads at hatching, I disagree. I believe that the gray heads is NOT an expression of melanin in the skin, but rather the darkness of the skull and eyes passing through the head. As the animals age their skin thickens and you can't see the color passing through any more.

Here's a quote taken from Wilkepedia:
Leucisim is one of two conditions that produces apparently anomalous white animals from parents that are otherwise normally coloured.

Leucisim is often mistaken for albinism, due to the similarity in the white colour exhibited by some animals. Leucistic animals lack all colour in their skin, fur, and feathers; but have normally coloured eyes. Like albinism, leucisim can be inherited by offspring, though not as consistently or reliably, and the gene does not appear to be fully recessive as is the case with albinism.

While albinism results in an animal lacking the normal melanin (and occasionally other) pigment cells, leucistic animals retain the cells; but lack an enzyme needed to activate the pigment. Albino animals -- most notably reptiles and birds, though the phenomenon has some parallels in fish as well -- can still retain colour from erythrin (red-orange) and xanthin (yellow) pigments; unlike leucistic animals, which do not have any active pigments.

Another key difference is that leucisim can also be localized and incomplete, affecting only part of the animal (whereas albinism, anerythrism, and axanthism always affects the entire animal); with irregular patches of white on an animal that otherwise has normal colouring and patterning. This produces what 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.

Not too sure where you got this info from but it is not true....

Leucistic ball pythons??? They have those now too??? LOL
Leucistic alligators are all white with blue eyes..... Same with rat snakes and even leucistic nile monitors.... They do not have the same characteristics as blizzards

Ya see, you cant compare bird and mammal genetics with reptile genetics.....

Actually Chad, leos do have scales..... They just aren't overlapping scales....

I think that Xaviers definition of leucistic is pretty spot on.....

why? what it comes down to is genetics. they all work the same. how else can you explain albinsm in everything from humans to mealworms?

the scales of leucistic snakes are white while thier skin is typically grey in color. (didnt i already mention that?)

True, but it is expressed differently in different families of animals......
 
Also forgot to mention that blizzards can have anywhere from small to large traces of yellow pigment which does not occure in any leucistic animal....
Cool pic by the way Chad.....
 
Mmm... yeah, but then why do Canada Geese and Adelie Penguins show up as chocolate leucistics? Maybe leos are expressing leucism that way, except they're using yellow instead of brown. And I wish I could find my reference for the leo community bit. Darnitall. *digs around*
 
ok so the animal normal sold as luesictic is really a paternless and the thing normaly sold as a blizzard is really a luescistic? And what are the prices they are going for approx.?

Yeah but they can also have carroting in the tail so they whould have to express red as well..... Highly doubtful in a leucistic reptile or any leucistic animal for that matter..... Oh and some even develop black spots.....

Some are purplish, grayish, yellowish, blackish and whiteish.....

It is a pretty safe bet to say that blizzards are not leucistic leopard geckos....
 
The problem with that reasoning is that coloration in leos is not strictly genetically based. It has a LOT to do with temperature. Look at the chocolate albinos. If you didn't know better, you'd say that those albinos were depositing melanin in their skin when they're exposed to cold temperatures. Some of these darker blizzards with or without spots could be due to temperature variation either during incubation or life, not genetics.

This thinking doesn't seem right to me even do there is varation there is still bonderies such as albinos unable to produce black pigment
