What defines a 'sport' in rabbit breeding?

In rabbit breeding, a 'sport' refers to a rabbit that exhibits a variation in color or pattern that is different from the standard for its breed, and these variations often include color mutations that are not showable or accepted based on the breed standards. This means that a sport would typically not conform to the expected traits recognized in exhibition settings, such as being a solid color in a marked breed.

This definition is important because it helps breeders identify and classify rabbits that may have unique traits or characteristics but do not meet the established criteria for competitive showing. Understanding what constitutes a 'sport' can guide breeding decisions, allowing breeders to strategically develop their stock while also acknowledging that not all variations will be suitable for the show ring.

Other options do not align with the definition of sport in the context of rabbit breeding. A variety being championship worthy or able to compete in all shows would indicate a standard show rabbit, while a breed known for health and longevity touches on overall breed characteristics rather than the specific classification of a sport.
