colour question.....

What possibilities are their from the mating of:

sire homozygous black agouti hetrozygous

mare black tobiano hetrozygous carries red factor but agouti negative,

obviously I won't get a chestnut foal but can I still get a bay tobiano? or bay? if the sire passes on his agouti gene?

Sire is EEAa
Dam is Eeaa.

You are right in that chestnut is not possible. ALL foals will be black-based. Of those, 50% will be black, 50% will be bay, or some form of bay/wild bay/brown depending on exactly what state the Agouti is in.

On top of that, 50% Tobi. This translates to 25% black, 25% black Tobi, 25% bay, and 25% bay Tobi.
