Wow! It´s so great, another
Wow! It´s so great, another Horse in that colouring :) Yes, I promise, I am going to test him! He was sick a long time, so I completely forgot about it! But now he is fine again :) I am searching for a german lab and then send the samples in! Very curious about both our results! :) I will test him only for gray as well :) Greetings from Germany ;)
My friend has used this
My friend has used this animalgenetics.uk, she has only nothing else but good things to say about that. She has small finnishnhorses that are tested to be splashing white.
I am eagerly waiting for those results. The color of my horse and your horse are so similar and maybe kind of rare. I have never seen this kind of colored horse before. And there are lots of people in Finland who are amazed about the color of my horse.

No, Gladiador TNF is a true
No, Gladiador TNF is a heavily expressed rabicano. Note how the white is concentrated in the flanks and the large area of white hairs at the tail head.
I'm not sure about the mare. My first impression is yes, it is the same delayed graying but they say both parents are solid brown? It could be that the parentage is wrong, one of the parents is indeed gray but grayed slowly so wasn't registered as such, or it could be something entirely different. I am confident that the 20 yr old gelding show further down the page is indeed the delayed gray that we are seeing.
The one similarity between
The one similarity between all these horses (not that Gladiator) but Tiagos horse, my horse, that one pony and those two horses in the page that Tiago linked, is that they all have lots of white hair in the area of their neck. There is also more whiteness in the fore of the horse than the back. My horse also has that "skunk tail", what about your horse Tiago?
This becomes more interesting than I thought :)
I'm thinking this must be
I'm thinking this must be inherited as a dominant mutation that has no effect if gray is not present? That would leave about 25% of a the offspring of a horse that is heterozygous for both gray and the mutation that would also appear to "gray slowly".
That is about what we are seeing isn't it?
A mutation such as this isn't unheard of...In cats there is a "Dilution Modifier" mutation that has yet to be located that only affects color if dilution is also present, in dogs there is Harlequin that only affects pattern if Merle is also present. and in mice there is Dilution Inhibitor that reverses the affects of Dilution.
What do you guys think? Should this be termed Gray Inhibitor?

That sounds logical also to
That sounds logical also to me, although I´m not so familiar with all that genetics stuff. I want to add couple of older pictures of my horse, in those pictures you really can see, that the amount of the all white hair has increased hugely during the yrs.
The first pic - my horse as foal with his mother. This pic is taken in 2001.
The next picture is from 2006, there are couple of white hairs in his forehead, l little star.
The thirs one is from 2010. In this picture you can see that the "coming" of all white hair have really started.
Exciting, waiting for the results of the gene test... *dance4*
Oh can't wait to see the test
Oh can't wait to see the test results!
I just finished an article on this. I linked to this thread at the end of the article.

Lovely pictures
Lovely pictures Tiago. I can clearly see that your horse has also been much more darker before. When I am thinking the coloring about my horse it seems that at first he has been a bit lighter bay and then became darker before this whitening started.
Still waiting the test results, will tell you those asap!

The sire
Hello! Got some information about the sire of my horse. No DNA-test done, but the most likely is that the sire is Estonian horse stallion called Rokkar.

Rokkar is silver black.
My horse looks quite white nowadays :-)
Is the bay horse pictured
Is the bay horse pictured here http://www.sukuposti.net/hevoset/torma/… his dam?
If so, either she was a late grayer herself or the sire is wrong. The sire most likely didn't have gray because silver + gray tends to gray very very quickly sometimes even being born already white.
I will test
I will test him, gray seems to be the only possible chance. I am going to take the samples tomorrow and post those during this week to the www.animalgenetics.eu. My friend has used this lab and she has only goos experiences of it. I will tell you what the answer will be.
It would also be very interesting if Tiago92 could test her horse? The markings of these horses are so similar, unbelievable similar.
Waiting for the results... :)
