Rabicano

Hello :) i would like to learn more about the colour of my horse. He ist a 10-year old purebred spanish stallion. I assume he is a rabicano but i find really little Information about this colour- especially when i am searching for spanish horses. I know that there is a stallion in uk, comico iv. Comico and my horse share the same bloodlines. Probably Devoto II carries this rabicano gene, but i just assume that. So , if someone knows about this colour and can tell me more about it or can tell me if my horse is really a rabicano please help me ;) and i say sorry for every gramatical mistake i made and will make - english is not my mother tongue ;) thanks :)

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... :)

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 ;)

It is safe to write down the cardnumber etc. on the paper for the payment? Do you have experiences with it? Because when I am going to send them to the UK, I want to be sure about that :D Never made a transfer to another country, honestly... ;)

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 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 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 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?

Yes :) Even if I do not understand anything about genetics, that sounds logical for me :)

Tiago92 Fri, 12/06/2013 - 12:14

By the way, here are Photos of the Brindling of my Horse, sadly the photos are a bit too light - in nature it is more visible.

blanka Fri, 12/06/2013 - 13:52

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*

 

Tiago92 Wed, 12/11/2013 - 12:28

Finally!!!! :D I got pictures of my horse when he was young, look how dark he is (even if he was just under the shower ;) ) And one pic a few years later ;)

blanka Sun, 12/15/2013 - 11:44

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!

 

*dance4*

blanka Tue, 12/17/2013 - 13:03

Tadaaa!!!

 

The result of the gene test came today. It says that:

 

" Heterozygous. Horse carries one copy of the Grey gene"!

So, what does it really mean? You are wiser than me, so tell... :)

 

 

Daylene Alford Tue, 12/17/2013 - 14:13

*Happy Dance*  It means that your horse probably has the gray inhibitor and will follow the same graying pattern as the Comicos.  

I so wish we knew the sire.  

blanka Fri, 01/03/2014 - 13:48

I so wish that I knew the sire, too. I´ve been trying to contact horse people in Estonia, but no succesm yet...

blanka Mon, 04/06/2015 - 14:53

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 :-)
