Lindsey,

Not a problem I love Equine genetics, reproduction and nutrition. One day I will finish school on it all. (after my boys get a little older). I had my mare tested at the end of last year, and was surprised that she carries the agouti gene and she is a palomino tobiano paint. The reason I was not sure on your mare is I know you say she is a bay, so that is what I ran the options as, but registered as a red roan. The only reason I might second guess it is that my friend has a dun mare, anyone who looks at this mare says she is just a dun, but she was registered as a red dun. She has had babies and always thrown palominos but she was breeding her to a bay stallion this year and was concerned about the coloring and if she would need to re-register the mare. She re DNA tested her and the AQHA went back through their records and DNA information and sure enough she may look like a standard dun color to the eye but her genetics don't lie and she is a red dun. Now that she has shed out you look at her points and they are not a true black but that burnt black or dark dark red color.

But the testing center I use has a website and that is where I got my information. It is a fun site to play on. Once I got my mares info back and put hers and the stallions in that she was bred to my results were:

12.5% chance of one of the following
palomino tobiano
palomino
Chestnut tobiano
chestnut
6.25% chance of one of the following
Smokey black tobiano orsmokey black
buckskin or buckskin tobiano
black tobiano or black
bay tobiano or bay

So really it breaks down to (color only not adding tobiano pattern) 25% chance of either a palomino or chestnut color, 12.5% chance of smokey black, buckskin, black, or Bay. We ended up having a Bay Tobiano filly. Go figure we were betting on a chestnut. But we love her anyways

It is a fun site to play with. www.equinecolortesting.com
