I also breed a lot of rodents and play with the genetics a little. I have read what I can find. What would you say the difference would be between a Hypo gene and Dilute gene in snakes if the dilute gene existed? I know how it acts with the Blue Rats for example, but are we calling the same basic type of gene by two different names in the Rodent World and the Corn Snake World?
Well there are a number of dilution type genes among mice. Let me name those first, and then we can see if there is some sort of parallel.
The major is on the C-locus. I have an entire "article" I wrote about this gene found at my mousey website:
http://www.geocities.com/mousedomousery/ the link will be at the bottom of the home page.
Among the genes on the C-locus are:
C - Full color
c - full albino (no pigment)
c(e) - An extreme dilution gene
c(ch) - chinchilla gene (eliminates yellow)
c(h) - Produces an acromelanic effect... himalayan and siamese
I am probably forgetting a few c-alleles
Also among the dilution genes is:
p (creates pink eyes and dilutes the coat colors of the mouse)
I'll have to go through my genetics site to remember the genes (it's been a while since I've reviewed) ....
e (creates a yellow coated mouse... no blacks or browns)
d (creates a blue coated mouse ... no yellows or browns)
b (creates a brown coated mouse... no yellows or blacks)
Now the albinism in snakes doesn't really correlate to albinism in mice. c(ch) would be a charcoal corn. c(e) would be a hypo, e would be another type of hypo, and b would be a third type of hypo. p would be a fourth type of hypo the way we are discussing such things, as these all reduce or eliminate the black pigment.
An acromelanic gene doesn't have a strong correlation to a cold blooded creature. This causes pigmentation in the cold extremities of the mouse, but white/albino in the rest of the mouse....
There have been efforts to take a normal spotted (piebald or cow mouse) and get a tri colored mouse. There are a few "legitimate" ways of getting this, but the look that mouse breeders are trying to acheive is something like the paradox albino.... normal colored but a few splotches of other colors. They've achieved this through genetic manipulation, and a few mice are born just with aberrancies. But most often these turn out to NOT be genetic.
As far as the T+ albino, I would say that your lavas meet the definition. BUT Lava is a better name.
I'll have to look through my website later, and then try to see what parallels I can find. This is all just off the top of my head and I must run. Feel free to check out my website... it's old, I haven't updated it in a while, but most/all of the genetics stuff is backed up by research on the jackson labs website.
