I will be travelling for work approximately August 4th to September 4. So if you want bones from my shop now is a good time to order. I’ll even throw in a free necklace if you buy a skull or set of skulls within the next 7 days.
Also, I would love for you to let me know if you have any recommendations of things to do in Chicago, New York, Houston, and Los Angeles. Especially if it’s transit accessible. I’ll have my camera and will blog anything appropriate.?
Leucism is a reduction of all pigmentation, where as Albinsim is just the absence of melanin. So in animals that have other pigment cell-types as (in addition to melanin) can result in an Albino that is not entirely white—a good example is pythons, Leucistic Pythons can be pure white, but Albino ones are yellowish because only the melanin is gone, and they have other kinds of pigment in their bodies. Melanin only affects skin, hair, feathers, scales, and eyes. Some animals, like domestic cats, have a different structure in their eyes, so some albino cats will have blue-ish pink eyes instead of completely pink/red eyes.
Leucism affects all types of pigment, but only in the skin, feathers, etc. Which is why a Leucistic Python can be pure white. So Leucistic animals often still have dark parts of their body though, like brown eyes or black noses in mammals (though many can still have pink noses, or blue eyes, or other “albino”-like features).
Leucism is caused by a disruption of the flow of pigment to anywhere on an animal. This can cause only one pigment to be dumped, or all. So yes, pied animals are partially Leucistic.
Now about the pattern mutation vs. Leucism. I haven’t read as much about it, but it appear that many pattern mutations I have seen are linked to a color mutation like the ones we’ve been talking about. When in doubt (as I am no expert) I rely on what a more noted source says.
Pattern mutation can be a tricky beast to identify as it wasn’t until recently that scientists even knew what caused King Cheetahs to look as they do! Science can still be fluid and changing in these respects.
A great explanation! You can see a diagram of color morphs here.
