Possible WC hypo

[Stefan-A]

I agree with Udo. And in part with James and Shannon, I think. If I understood them correctly.

In my opinion, even if albinism is usually characterized by amelanism and hypomelanism (most notably in mammals and birds), it's a gross oversimplification to call an amelanistic or hypomelanistic animal an albino. As bad as calling a hypo-/anerythristic or hypo-/axanthic animal that.

Fun discussion by the way James!

Yeah, I really enjoyed it! I'm no wiser, but it was fun.

There is a lot of inimitable beatyfull specimens, like Bill´s, even in the type of T.s.sirtalis.
To call them a morph there should be an occasion for planed breeding.
This will be really hard for those phenotypes that are based on multiple allels.
I know thats there were a lot of spectacular specimens in Scotts breeding stock that are not bred any more.

So, because of what Udo said, "Albino is lacking of pigment on mamals!
Reptiles are amelanistic, anerythristic on axanthistic," there is no such thing as an albino snake and we should be calling that an amelanistic snake?

Do I understand that correctly?

[infernalis]

Gertie, all those terms each have a different definition.

Oddly, a pure "albino" is called a snow. (Lacking any and all pigmentation.)

amelanistic = Lacking black
anerythristic = Lacking color, but black is present
axanthistic = Unknown word
Melanistic = all solid black

and variations on the above...

[Stefan-A]

axanthistic = Unknown word

Axanthic. Lack of yellow.


amelanistic = Lacking black, but red and yellow is present.
anerythristic = Lacking red, but black and yellow is present
axanthic = Lacking yellow, but black and red is present.

Combine all three traits and you get one without black, red and yellow. At least in theory.

Thank you Stefan

[zooplan]

a: amelanistic = Lacking black
b: anerythristic = Lacking red
c: axanthistic = lacking yellow
d: melanistic = (all solid black) black covers other colors
e: erythristic= red covers other colors
snow= combination of a and b
blizzard= combination of a, b and c (real albino)

oh, I´m to slow again ;-)

[Stefan-A]

blizzard= combination of a, b and c (real albino)

That would be my interpretation as well.

[infernalis]

b: anerythristic = Lacking red

So why would a Anery red sided garter be desirable??

Or an Anery infernalis?

Yet for some reason folks are willing to pay good money for a red sided garter that has no red on it?

I understand, unusual and different appeal to many, including me.... But red is a fine colour, and why anyone would want it gone escapes me.

Oh, and thanks Udo, my comprehension of these terms just leaped forward
