Appearance
| Foals |  |
Light yellow/golden coat color with primitive markings. Mane and tail are lighter in color. |
|---|
Chestnut base diluted to a yellow or gold color. Mane and tail are turned into a creamy shade and can be nearly white. Primitive markings are present, but can be harder to see. |

Mimics
Primitive markings are often more difficult to see on dunalinos, especially the dorsal stripe, which can sometimes appear not to extend through the tail. Dunalino can therefore be confused with palomino or palomino nd1. Darker shades of dunalino can look similar to chestnut dun.
Genetics
Dunalino is the result of a chestnut base diluted by one copy of cream and one copy of dun.
The cream (CR) dilution is an allele of the MATP gene. The dun (D) dilution is an allele of the TBX3 gene.
Dunalino:
Chestnut (e/e) + CR/n + D/_
