What is a "run" in the context of marked breeds?

In the context of marked breeds, a "run" refers specifically to a fault of white intrusion into color. This means that when a rabbit has a pattern that deviates from the breed standard due to unwanted white coloration appearing in areas where it should not be, it is considered a "run." Such markings can affect the overall appearance and breed classification, as show standards dictate specific acceptable color patterns.

Understanding this terminology is essential for evaluating the quality of marked breed rabbits in competitions. It helps dexterous handlers recognize and assess characteristics that may lead to penalization in show judging. In contrast to the other options, which pertain to size, ear defects, or behavior, the concept of a "run" is unique to color pattern faults in breeding standards, making the choice relevant and significant within showmanship practices.
