Which of the following describes a characteristic of a "breeder" rabbit?

A breeder rabbit is specifically described as one that is used primarily to produce offspring. This means that the main purpose of a breeder rabbit is reproduction, ensuring that high-quality traits are passed on to the next generation. Breeder rabbits are often selected for desirable characteristics, such as size, color, temperament, and breed standards, which enhances the lineage being produced.

In contrast, a rabbit that participates in shows regularly is focused on exhibition rather than breeding. Rabbits that are solely for pet purposes do not typically have a breeding focus and are kept primarily for companionship. Lastly, a rabbit with no defined characteristics does not align with the breeding goal, as breeder rabbits are chosen for specific traits that contribute to the quality and standards of future litters.
