For those of you not on FaceBook or just not in the Genetics group I have started:
I have had some people wondering about distinguishing blizzard eclipse vs what we consider 'normal' or Tremper eclipse. Especially in terms of why blizzard eclipsing in albino animals seem to keep the eyes black, instead of red.
The eyes are red in albino eclipse animals because we are seeing light reflecting from the back of the eye (the retinal pigment epithelium), where the veins and arteries are (hence why it is red, because of the blood.)
So here is a simple explanation that I thought of, that may help some understand the difference a bit better:
Think of the eye with layers. Now imagine having two layers of curtain on a window that has red tint on the panes. The layer against the widow is solid, and doesn't allow light to come through, and the layer on top of that is an accent color like grey (like the geckos eye.)
Normal eclipse peels back both layers of curtain and lets you see the red tinted light, where blizzard eclipse only peels back the accent curtain.
