What defines a purebred rabbit?

A purebred rabbit is defined by its lineage, where it is produced through successive mating of the same breed. This means both parents belong to the same recognized breed, ensuring that the offspring inherit consistent physical and behavioral traits characteristic of that breed. Breeders focus on maintaining these specific traits through controlled breeding practices to preserve the breed's integrity, appearance, and genetic quality.

The other options do not align with the definition of purebred. For instance, a rabbit with diverse genetic backgrounds does not have the consistent traits that come from a controlled breeding program. Similarly, random breeding would lead to a mix of traits and characteristics, which is not conducive to establishing a purebred lineage. Crossbreeding introduces genetics from different breeds, which directly conflicts with the concept of purity in breeding. Thus, the correct definition of a purebred rabbit is centered on the consistent breeding practices associated with a single breed.
