I have a ten month old filly that i think may be changing color as she sheds her first winter coat. Her sire was a black roan sabino (dam is just black). She has alot of white hairs starting to grow in her mane, tail and muzzle.

Here are pics
Muzzle:-

Mane:-

Tail:-

She was born this color . . .

Almost like a red dun (she even had a dorsal stripe)
then here is a pic of her from this winter

I would love for her to be turning roan, but i dont want to get my hopes up. Has anyone seen changes like this before and have an idea of what she may turn out like?

Elizabeth,
I cannot be of too much help here, but I do know for sure, that she is not turning roan.
Roans do not gray out on the face or lower legs. (I don't think the mane or tail either) The dorsal stripe you said she had when little, was just counter shading. Not a true dorsal stripe.

I'm going out on a limb here and saying I think your filly is going to end up Chestnut with the Sabino gene.
Very pretty girl!

Elizabeth,
She doesn't look so much like she is "roaning" as she is getting a lot of flaxen color in her mane and tail. This is not uncommon with sorrel horses, particularly light sorrel which is what I would call her. Their muzzles are typically light colored too.

A greying gene may also be present, and that can affect coloring in varying degrees however, I think she would be roaning out all over. It appears so far her body color is staying "hard".
Once she sheds her winter hair completely you may be able to tell more about her body color.

When she was born we didnt think she had the sabino gene, since she only has the two rear socks and the stripe on her face, but I did a little bit of research and figured she could just be minimal sabino.
either way its going to be interesting watching her change, and she's such a sweet girl, her color isnt that important.
Thank you for the replies :-)

Well if her sire and dam are black based horses and she came out a sorrel, neither of them are HZ for black. She isn't a true roan, she looks to have the sabino gene.

I don't think she's got sabino. Don't sabinos have to have a white chinspot to be true sabinos?

Sabinos dont need a white spot on their chin to be sabino. All white markings not from splash frame or tobiano are thought to be from some from of sabino.

She most likely has some sabino roaning, and looks to also have rabicano roaning.
