Which term is defined as the brightness and brilliance of fur?

The term that refers to the brightness and brilliance of fur is "luster." In the context of rabbits and their fur, luster describes the sheen or glow that gives the fur a visually appealing quality. A high luster indicates that the fur has a shiny, vibrant appearance, which is often desirable in show rabbits as it signifies good health and proper care.

Understanding the importance of luster can help rabbit breeders and exhibitors in evaluating the quality of their rabbits, as it reflects grooming practices and the overall condition of the animal. Fur that lacks luster may appear dull or lifeless, which could imply neglect in grooming or potential health issues.

The other terms listed do not pertain specifically to the quality or appearance of fur in the same manner. For instance, "meaty" generally refers to the body condition or fleshiness of an animal, "molt" describes the process of shedding fur, and "marked" refers to specific color patterns or markings on the fur, none of which relate to the brightness and brilliance characteristic described by luster.
