What does the term variety refer to in rabbit breeds?

In the context of rabbit breeds, the term "variety" specifically refers to a classification based on color. In the world of rabbit breeding and showing, breeds are categorized into different varieties to distinguish them not just by their overall breed type, but also by specific traits within that breed. Color is one of the primary and most noticeable traits that can vary within a breed, leading to different varieties. This allows judges and enthusiasts to recognize and classify rabbits whose only difference may be their coat color or pattern.

An example can be seen with breeds such as the Holland Lop or the Netherland Dwarf, where individuals of the same breed may be divided into varietal categories like 'black', 'blue', 'white', etc. This classification helps maintain standards and allows for fair competition during shows, as it acknowledges the importance of color variety in the overall appearance and appeal of the animals on display.
