If you mare is not a red dun with the dorsal stripe and other dun charateristics then there is no chance of dun, as a dominant gene one parent must be a dun to pass it on.
The base colour all depends on the stallion here, do you know what colour his parents are and relatives further back? Or has he sired a chestnut from a reasonable number of foals?
If he does not carry chestnut then you will not get a chestnut from him only a black base colour.
It then depends on his Agouti genes that change black to bay or black and tan. if he has two of them you will only get bay or black and tan, if he has one you could get a black.
If he does carry Chestnut your chance of a chestnut will be 50/50.

I HAVE A DARK DUN(AS STATED ON HER PASSPORT)/BUCKSKIN MARE OUT OF A GREY MARE AND A CHESTNUT ROAN STALLION, THEIR IS DUN/BUCKSKIN IN HER BREEDING A FEW GENERATIONS BACK SO I THINK THATS THE ONLY PLACE IT COULD HAVE COME FROM.
HER FOALS ARE SLIGHLY DILUTED COLOURS TO THERE FATHERS, BLACK STALLION PRODUCED A BAY AND A DUNNY BROWN AND CHESTNUT PRODUCED PALE CHESTNUT WITH WHITE MANES AND TAILS, KEEP MEANING TO DO A COLOUR TEST BUT NEVER GOT ROUND TO IT.
I WAS GOING TO TRY A CREMELLO STALLION ON HER THIS YEAR.

I WAS GOING TO TRY A CREMELLO STALLION ON HER THIS YEAR. Yes sounds like buckskin, most UK societies do not know the difference! Cream in single dose has no real visible effect on black hairs and particularly Cream on the Black and Tans can easily be mistaken for "dark bay". It sounds like she might well be a single cream and if you do not want double dilute then I would test her before you breed to the cremello as you would have a 50% chance of a double dilute with that mating and 50% single dilute. Just out of interest here is the result of a survey on New Forest pony colours my sister and I did last year, bottom of the page www.brushbow.co.uk/src/speciesmenu.htm |

The sire parents are both bays That certainly raises the chance that he is homozygous for black base but chestnut can hide behind for lots of generations so never say never, but the foal will be a chestnut carrier for future reference. |
