How is a breed of rabbit defined?

A breed of rabbit is defined as a class of domestic rabbits that share distinctive traits, which can include characteristics such as size, fur type, color patterns, and behavioral traits. Breeds are typically recognized and classified based on these specific, inherited traits that distinguish them from other breeds. This classification not only reflects the physical characteristics of the rabbit but also may encompass other factors such as temperament and adaptability to certain environments.

The other options do not encapsulate the true definition of a breed. Simply being raised in captivity does not contribute to the definition of breed, as many animals in different settings can be of the same breed. Defining a breed strictly by color is too narrow, as it ignores the broader range of traits that also play a critical role in breed identification. While some rabbits may be designated for competition showing, this does not inherently define a breed, as not all rabbits are bred for this purpose, and showing is just one aspect of many breeds. Thus, the emphasis on distinctive traits in defining a breed is essential for understanding the classification and characteristics of different types of rabbits.
