Which of the following describes "variety" in relation to rabbit breeds?

The concept of "variety" in relation to rabbit breeds specifically refers to a subset defined by color. In the context of rabbit genetics and breed classification, variety is used to categorize rabbits that belong to the same breed but differ in their coat color or pattern. For example, within the breed of Holland Lop, there might be several color varieties such as black, blue, and tort. This classification recognizes the diversity within the breed that is attributed to color differences, while still maintaining the overall characteristics that define the breed itself.

Recognizing varieties based on color allows breeders and exhibitors to identify and showcase specific traits that may appeal to judges and the public during shows. Keeping this in mind helps understand the complexity of breed standards that encompass more than just physical characteristics like fur texture or conformity to breed standards.
