Anyone know mouse genetics?

[carol]

Just curious why this girl has red eyes???

I think that mouse is a champagne.

There are two different genes that can cause red eyes. One is the one that causes red eyes and a white coat, the other causes red/ruby eyes and just a lightening/dilution of the coat color.

I could be wrong, but that's my understanding.

I know rat, mouse and cornsnake genetics, which I just decided to look up out of curiosity.
The RED gene, (red eye dilute) also dilutes coat color. Her parents must have both carried the RED gene, if they didn't have it themselves.

Thanks! I just figured I had an Ultra/Amel mouse! :rofl:

If you blow on the fur of the mouse (blow from tail towards head) and see blue or dark roots to the hair, ti's an Argente mouse (a pink eyed dilute of the wild colored agouti) if it's yellow to the roots, then it could be a pink eyed dilute of a yellow (which doesn't result in any diluting factors, as yellow is not diluted by the pink eyed gene).

The other "gene" that causes pink eyes isn't really a gene for pink eyed mice, it's the albino (amel) dilute that causes an all-white coat, and removes all melanin or pigment from the coat.

If you really want to check out mouse genes, you can check out my website:

Thanks!
I blew on her and she is yellow all the way. I guess I have a yellow mouse with a dilute gene. I really appreciate your help and I can't wait to have sometime to check out your website. Maybe I'll be able to figure out what the others that I have around here are.

Hey, glad I could help...so she is either a yellow dilute, or a champagne. Hard to say from pictures.

Noticed you were from the Bay Area. I grew up there... in Cupertino.

As far as the mouse genetics go.... figure it this way... I bought hatchling snakes in '01, and wanted to breed them. So from then until the spring of '03, I could only study and learn from breeding the mice...once the snakes started breeding, I spent a lot less time on the mice. But mice are still a lot of fun!

Neat! I have several like her that popped out here in the last few generations. I always called them Hypo Mice, cause I couldn't really explain the colors and eyes.

So you mean if I take pics of the "odd ball mice" I turn up you can help me ID them?

I've got red hairs with red eyes, red hairs with black eyes, mocha color with black eyes, black with red bellies, champagne with red bellies...

Here is a newer pic of her and her man. :dancer:

i would tend to agree that it is a champagne. ive got black and whites, solid blacks (the black offspring get fed to the snake), and champagne and whites. out of these i get: black and white, black with a brown belly, agouti, agouti and white, champagne, champagne and white.
The pairing that causes the champagne coloring and the ruby eyes is a dilute of the agouti gene. Not to be confused with albinisim, which is being phased out even as lab animals due to early develoment of cancers.

Actualy if you are getting Agoutis from the "Champagne" bred to Blacks then your "Champagne" is actualy an Argente. A Champagne is a pink eyed Chocolate therefore a self x self can not produce an agouti. An Argente is a pink eyed Agouti.

The equivalent genotype/phenotype exists in mice and rats.
