What does "sweep" refer to in terms of a rabbit's markings?

"Sweep" in the context of rabbit markings refers to an unbroken flow of designated markings. This method of marking is characterized by a smooth and continuous transition of color or pattern across the body of the rabbit, creating a seamless appearance that enhances the overall visual appeal of the animal. A sweeping marking style is often sought after in show rabbits because it conveys a sense of harmony and uniformity that is desirable in breed standards.

The other choices describe different types of markings or designs that are not consistent with the concept of a sweep. Disjointed patterns with gaps would indicate a lack of continuity, while a clear distinction between colors would emphasize sharp contrasts rather than fluidity. A patterned design that is irregular would also detract from the smoothness associated with sweeping markings. Thus, the essence of a "sweep" lies in its flowing, cohesive visualization, making the selected answer the most accurate representation of this trait in rabbit markings.
