Which breed is indicated by the abbreviation "TN"?

The breed indicated by the abbreviation "TN" is indeed the Tan. The Tan rabbit breed is characterized by its unique coloration and pattern, which involves a tan body with darker markings usually found on the ears, nose, legs, and around the eyes. This distinct appearance helps in distinguishing it from other breeds.

The other breeds listed have their own specific characteristics and abbrevations that differentiate them. Silver Fox rabbits have a distinct coat that is soft and has a unique color pattern that does not correspond to the abbreviation "TN." Satin Angoras are known for their long, luxurious fur, which is also not indicated by "TN." Lastly, while Satin rabbits do have a unique sheen to their fur, they do not share the tan coloration that would correspond to the Tan breed. Thus, the correct association of "TN" with the Tan breed is validated by its distinct physical characteristics.
