Sabino Markings
 
I posted quite some time ago about how Rodeo seemed to be "greying out", or even "roaning". I was told that it was just due to sabino markings.

I know all of these markings are brought up a lot, so sorry if this has been answered before....but,
1. does he have sabino markings?
2. will he continue to lighten up, eventually going white/grey in large areas?

Here are some recent pics....

Thanks!!!

From Wikipedia: This refers to Rabicano which is what your extra white hairs look like to me.

Roan, rabicano, and sabino
Main article: Roan (horse)
http://upload.wikimedia.org/wikipedi...px-RedRoan.jpg http://bits.wikimedia.org/skins-1.17...gnify-clip.png
This true or "classic" roan has the characteristic darker head and legs.


A true roan is neither sabino nor gray, but instead refers to a pattern of evenly-interspersed white hairs on the body with minimal white hairs on the head and legs and few, if any white markings. The primary characteristics of sabino are white markings on the head and legs, often with roaning at the edges. When both roan and sabino are present in the same horse, it can be difficult to tell whether the roaning is due to sabino or true roan, especially if the white markings entirely cover up the telltale dark head and legs.
In some breed registries, the term "roan" is used to record sabinos, particularly with thoroughbreds and Arabians. Sabinos or sabinos with roaning have also been described as "roan" by Clydesdale, Shire, and Tennessee Walking Horse registries.

The extensive roaning or ticking of this horse's barrel is typical of the rabicano pattern, which is sometimes confused with sabino. High white markings and patches are not controlled by rabicano.


Rabicano is another type of "roaning" or ticking characterized by scattered white hairs centered around the flanks, barrel and white hairs at the base of the tail. Only in the most extreme circumstances is rabicano linked to underlying pink skin. It is unknown if the roaning characteristic of some sabino-type patterns is due to the additional presence of rabicano or a separate mechanism. Rabicanos are also often identified as roans, even among breeds that do not have true roans, such as Thoroughbreds and Arabians.

i almsot bet he stays overo.

Dreamcatcher....thanks for all that info! Helped quite a bit!

EthanQ.....I think that as well, a few friends at the barn noticed how he seemed to be getting more and more white hairs appearing, and I have as well. Didnt know if it was going to continue, or if it was a year to year thing.

Thanks for both of your posts!!!

It's not rabicano because he doesn't have a coontail.

Sabino + the fact that he's a sorrel will mean he will have white hairs come and go all over this body. Red horses tend to have little random white hairs mixed in with their coats. He's definitely not gray because neither of his parents are.

He's an overo chestnut for sure, but the rabicano seems to increase as the years go by. I love watching them turn into 'roany poanies'! Rabicano is very prevalent in Arabians and I love how it gives them some really cool frosting.

1) One of his parents would have to have rabicano for him to have it. Csimkuna, do you know what his parents looked like?

2) Rabicano is on the barrel and flanks of the horse, not the shoulder. I do know of a very rabicano Arab and he looks nothing like Rodeo.

I never said he WAS rabicano, I said that' what her extra white hairs made me think of and looked up the info for her. If she chooses to do some genetic testing I'm sure she can get a definite answer. In the meantime, I was under the impression we were all doing a kind of guessing game. Though I'll certainly defer to someone's obviously far more extensive expertise......

I'm sure since I only breed, raise and show Arabians and 1/2 Arabian Pintos I couldn't possibly have a clue......

You just said you thought it was rabicano. He's clearly not. And it's been discussed in other threads before that he's sabino.

As I said, I'll defer to your clearly proven superior expertise.
