TF .. a sabino gene didn't cause the color on the OPs horse. He is VERY classic varnish roan. He could have had a snocap blanket .. but he is a varnish roan.

As far as color. I'd say he is a black base (bay or black) appys can come in tri colors.. meaning they show both black and brown coloration.. usually a sign they are black carrier Ee and not EE

Interesting! No, his hooves are not striped. And someone else mentioned that there is the potential for a greater issue of eye or health problems with some of the colors being heterozygous. He does happen to have ERU (moon blindness) and he's only 16.

I am doing some digging. He was bred not far from me and was a stud until he was five. I know that he has some foals on the ground from then.
So I will hopefully get some backround info on him as far as breeding and color go. I have to dig up his papers for dam and sire info, but his registered name is Blaze n bright socks, for what it's worth.

Appy genes are fun!


TF I know that rabicano is not a pinto gene, but it is a "roaning" gene. Figured that it may be relevent. I may have to convince BO that she NEEDS to know what color he is and have him tested.

Well genetically he is homozygous LP/LP
And im nearly 100% sure he is a snocap.

My varnish roan filly (born solid and looked just like this gelding by 3 years) had moon blindness. She was helpless after dark .. lol. I had to "rescue" her more than once when she got left by her buddies in a new pasture she was unfamiliar with at night.

It was just a simple question, I was only wondering.


So, I read, and multiple sites told me varnish appaloosa have striped hooves and mottled skin, OP says this horse does not.
Also, as someone else pointed out, eye problems are associated with heterozygosity, yet a fewspot is homozygous?

I asked this before, but no one answered me; what is the genetic makeup f the pattern that causes a varnish appaloosa?

TF .. hoof color varies. Just like on a "normal" colored horse, if they have white legs, their hooves will be white. This is the same with apps. Also, being FS or snocap can affect the hoof stripes. Varnish can be present on any pattern, with any colored legs, hooves.

As a general "rule" Apps will have striped hooves, white scelera, and mottled skin.. there can be other factors at play.

I'm not sure of the exact genetics .. and I'm unsure of whether "they" understand the exact genetics of varnish roan yet. I don't know if it is it's own gene, or if it is "attached" to the LP gene. I just know how it is expressed.

Make sense?

I have my doubts about where I heard that it was heterozygous as being a sound source. Just to throw that out there.

I think it's homozygous .. but in my experience, I've seen more varnish roans with either moon or night blindness than any other color/pattern.

Again, my experience, and may not be the worldwide ratio.

He is not a fewspot...he could be a snowcap, but it is doubtful. He is however most assuredly a blanket/varnish roan.

Moon blindness is associated with homozygosity - not heterozygosity. It is believed that all homozygous Appys have moon blindness.

It is not unusual for Appy chestnut varnish roans to be very dark in the upper body, with the lighter brown only showing up in the legs. The picture below is one of my former linebred Plaudit broodmares. She is chestnut, but appears much darker. Notice the lighter brown on her lower rear legs, very similar to the one the OP posted...
