I think that your best chances are sorrel toby, solid sorrel or a bay toby. You have small chances of a black toby, black solid, depending on how the mare tests for a couple other genes.

Best chance I would go with a sorrel toby or a sorrel solid.

Good luck
Kim

Without knowing the recessive/dominance of the Tobiano or the Agouti....these are your relative expectations of offspring:
18.8% - Chestnut
56.3% - Chestnut Tobiano
0.8% - Black
2.3% - Black Tobiano
5.5% - Bay
16.4% - Bay Tobiano

I did the configuration on Animal Genetics...it allows you to plug in the sire/dam characteristics and gives the expected combinations.

Melissa alot depends on if the Tobiano stallion is heterozygous or homozygous, if he is homozygous you will gets a bay tobi or a sorrel tobi or rarely a black tobi, if he is heterozygous the above formulation is correct and its a toss up on what you get. add sorrel tobiano in the mix of the above formulation too.
