What defines a breed of domestic rabbit?

A breed of domestic rabbit is defined as a class of rabbits that share distinctive characteristics which could include their size, coat texture, color patterns, and ear shape. These characteristics are consistent within the breed and contribute to its recognition within rabbit fancier communities and organizations. This definition allows for a variety of traits that can be seen across individual rabbits of the same breed, making it important to understand that breeds encompass more than just physical attributes—they also include behavior and temperament that are common among the rabbits classified within that breed.

The other choices don't accurately represent the concept of a breed. For instance, size can vary significantly within a breed, so stating that a type of rabbit must always be the same size is too restrictive. Similarly, color diversity exists within many recognized breeds, which makes the assertion that a rabbit must be of a single color inaccurate. Lastly, defining a rabbit as an individual without distinct features does not align with breed classifications, which emphasize recognizable traits that unite individual rabbits of that breed. Thus, the first choice is the most fitting definition of what constitutes a breed of domestic rabbit.
