What defines "flyback" fur in rabbits?

"Flyback" fur in rabbits is characterized by a coat that quickly returns to a smooth position after being stroked. This quality indicates that the fur has a certain resilience and elasticity, allowing it to stand up when brushed or pet and then immediately fall back into place. This type of fur gives the rabbit a sleek appearance and is commonly found in several breeds, reflecting a healthy and well-groomed coat.

The other descriptions provided do not accurately depict flyback fur. For instance, a coat that remains flat when stroked suggests a different texture or type of fur that doesn't spring back, while a rough coat or one that is curly and does not lay flat would indicate other fur qualities that are unrelated to the characteristics of flyback fur.
