red dun?

I was wondering-- if Dun and a chestnut/sorrel makes a red dun, would a liver chestnut make a darker variation of red dun, or would you not be able to tell the difference?

No way to predict if it would be a liver red dun or not. No way to predict what shade of red a breeding will produce.

What would it look like, if it happened? Have you ever seen one?

They would produce a 'chocolate red dun' every time? Or could they have a light color red dun?

There is no guarantee on color shades with any breeding.

I thought since the liver had darker shades on its legs mane and tail-- it would react differently to the agouti than a light colored chestnut. Thanks for clearning that up.

Agouti doesn't express on a red-based coat. He's advertised as A/A because they will have tested him to see if it's physically possible for him to throw black or grulla. It isn't - to a homozygous black [E/E] mare with no modifiers [ie, plain black] he can only throw bay and bay [yellow, 'zebra', classic] dun. Depending on his dun zygosity.

Agouti on a black base gives you bay [or brown or wild bay depending on which type of Agouti you're actually talking about]. In that effect it's sort of the world's most common dilution gene! It restricts black to certain parts of the horse's body, therefore diluting the rest of the coat to a brown or reddish colour.

We aren't sure what determines the shade of red a red horse comes out as, certainly sooty can have a genetic factor and is implicated in turning a 'normal' chestnut liver, but the inheritance of the gene is thus far unknown, and having a gene and expressing it can be two completely different things.

My filly for example almost certainly has sooty. Her tail is almost black [photo does NOT do it justice] and her mane has black strands in it, but that's the limits to HER expression. She also probably has flaxen, given that she has a lot of gold and white in her mane as well as normal 'red' strands, shades of dark brown, and the black strands.

She's not dun, but she has a weak countershading dorsal stripe, which doesn't show up much in person but seems quite strong in photos taken from behind. Unfortunately I can't find the photo I have uploaded that shows it.

She's a Thoroughbred, and the dun gene does not [to my knowledge] exist in the breed. It's certainly not in her bloodlines on either side.

A chestnut horse without flaxen or sooty will have a mane and tail that match its body, or at least that's my understanding of the genetics.

And the below horse indicates how extreme sooty can be. He is chestnut.

Same gene [or so we believe], completely different result.

Here are two red duns I know, one is rather dark and the other is a rather orangey color (light enough to the point of being mistaken for my buckskin from a distance).
