What color will the foal be from a white stallion and chestnut mare?

It's impossible to say for sure what color the foal will be. Here's why:

* White is a complex color: A white stallion can carry hidden genes for other colors. A horse can appear white but actually be carrying the gene for chestnut, bay, or even black.

* Chestnut is also complex: While chestnut is a relatively straightforward color, it can have variations in shade and can also carry hidden genes for other colors.

Possible Outcomes:

* Chestnut: The most likely outcome if the stallion is truly white and carries no other color genes.

* Other shades of chestnut: The foal might be a lighter or darker shade of chestnut depending on the exact genes carried by both parents.

* Other colors: If the stallion carries hidden color genes, the foal could be any of the following:

* Bay

* Black

* Palomino

* Buckskin

* Roan

To figure out the foal's color, you'd need:

* More information about the stallion: Is he a true white (no hidden color genes) or a white-appearing horse with other color genes?

* Detailed knowledge of the mare's lineage: This can help determine if she carries any unusual or hidden color genes.

Horse genetics are complex, and even experienced breeders can't always predict the exact color of a foal!
