Champagne, on the other hand, is a simple dominant. Having two copies of the gene looks exactly the same as only having one.

ETA- And having one champagne and one cream looks very similar to having two cream genes; again, you'd have an almost white horse.

I am reading what you are writing, but I think it is just bouncing off my thick skull.

Let me see if I think I have this...
He is maybe bay based with only one cream (creme?) gene and still has wonky eyes, or he is something with a possible champagne gene, which only seemed gave him a green eye and one wonky eye??

*scratches head... still confused, just like in trigonometry class all those years ago...*

He's definitely bay based, and he definitely has one dilution gene (either a champagne OR a cream gene) but not both. They can both be very, very similar visually.

The eyes are a pretty good indicator that it's champagne, as is the fact that you say his legs are a not quite black.

But, a champagne should have freckled skin. Since he doesn't, that still leaves a tiny bit of doubt in my mind.

However, I'm not really sure what else would cause the hazel eyes. Having a single cream gene shouldn't change eye color at all, AFAIK. The pinto pattern that's causing the blue in the left eye only causes blue- it wouldn't cause hazel, either.

So I think your buckskin is not champagne but like my mare Joy who has amber eyes. She is not champagne but has beautiful gold eyes that are the same color as her coat. We have discussed her on the forum before as well. I talked to someone at the champagne organization via email and sent her pics. She said that she believes that is an extra modifying gene something to do with the creme gene that also affects their eye color. I can't remember exactly what she said at the moment I'll hunt down the email here in a bit. Then the blue in them is probably caused by splash/frame or both the white marking extending to the eye is like my friends frame mare.

Yes, I remember when the thread came up about her eyes.
My boy’s right eye has the same shade of amber, but only in the bottom ½ to 2/3. The rest (upper part) is ice green. He does have the white mark over that eye, but his blue/amber eye has no white mark near to it.

Hmmm, extra modifier gene?

So guys, is it possible that he is buckskin with the cream gene and this modifier gene that set the eye colors?
Or is it even possible that a gene can give only a partial expression? Like the champagne gene that affected one eye, but not the other… and no mottled skin either?

This has truly piqued my interest and I’m thinking I might just have to do the DNA test (thanks Chiilaa for the info) but honestly with the holidays coming, I doubt I’ll get them sent until after.
Anyone know how long it takes to get the results back?

And, since I’m sooo curious as to what exactly is causing the eye color, is it possible to have them check for champagne as well as “everything” he has color wise?
Try to find the “wonky” gene?
Do the tests work that way, or can they only look for one thing at a time?
Should I call them with my quandry and see what they have to say about the genetics and what they would recommend?

Green Broke
Im thinking single dilute champagne as well, but id want to see a wet photo of her in the summer, to look for freckling, as well as a close up of her face in the summer, I knwo the blue part comes from spash, as her blaze is bottom heavy and tips over her nose.

I don’t have a lot of information about his genetic background and am wondering if anybody has some insight on what might have made his eyes so different.

He is an 8 year old Rocky Mountain Horse. These are the horses that are sometimes chocolate or chocolaty dappled (technical terms ) in body color with long flaxen manes and tails.
Mine however, got neither the chocolate or the flowy hair! LOL

Because I’m not sure what might be helpful, here are some color things about him-
He’s a buckskin, and if you divide him in half (front/back) there are some coat differences.
While it doesn’t show up well in pictures, if you look in person at his back half you can see all the hairs on barrel, flank, and rump are the same deep dark consistent gold color.

If you look at the front half, from just behind the shoulders forward, the hairs begin to “roan” with medium gold hairs mixing with the dark gold.
The further front you go, the more roaning there is… right up the neck with the cheeks/forehead and uppermost neck being a complete mix of light/pale gold hairs mixed with medium and dark gold.
It is more visible in his winter coat, but is still present in summer sleeknees and his entire head is a shade or two lighter than his body, especially the back half.

On his face the lighter hairs/roaning occurs mostly on the forehead, above the eyes and his cheeks.
Below the eyes, towards the front of his face he is darker gold.

He does have three or four pea sized white spots, but I figured they were little scars since they are sort of scattered around in odd places, but... on his chest and neck, the lighter hairs sometimes group together to form small faint "patches." (not dapples, but he does get those too)

Ok, the actual eyes-
The left eye is brown/amber and blue and is on the non white mark side of his face.
The right eye is icy green at the top and light amber in the middle and the bottom.
It can be hard to see as he doesn't open his eyes fully very much for the camera and in a picture with a strong flash, the icy green part appears to look like polar ice, but to the naked eye it is indeed an icy/minty green color.

Any ideas why he has such odd eyes??

I love the unusual eye color and his lovely coat color

LOL! First thing I thought of when I saw the Title of this thread. Jimmie Driftwood wrote & sang Tennessee Stud and then a bunch of others covered it.

Sooo I don't know if this is possible but I just had an idea as to why your horse has green eyes. Let me know what you guys think! So I talked about how the modifier gene with creme that diluted joys eye color as well as her coat making her eyes amber or gold. Your buckskin has blue in it's eye from frame or splash and perhaps some of the blue was diluted as well. Mixing blue and yellow is how you make green ! So maybe you it's something simple like that!

Interesting idea....
Anyone know if that is possible?

I don't think blue eyes in horses can really be diluted as what frame or splash does is covers up whatever the original eye color would have been with the blue.

Normal brown? Replaced with blue.
Diluted brown? Replaced with blue.
Champagne hazel? Replaced with blue.

That's just what logically makes sense to me though...I'm more of a coat color person.
