What characterizes an albino rabbit?

An albino rabbit is characterized by having white fur and pink eyes. This pigmentation occurs due to a lack of melanin, which is the pigment responsible for coloring in fur, skin, and eyes. In albino rabbits, the absence of melanin in their fur results in the pure white coat, while the absence of pigment in the eyes leads to a pink appearance.

The other choices describe rabbits with variations in fur color and eye color that do not correspond with the definition of an albino. Brown fur generally indicates some pigmentation and is not compatible with the definition of an albino, nor would gray fur fit that characterization. Blue eyes are not typical for true albinos; pink eyes are the definitive characteristic for this type of rabbit. Understanding these specific traits helps in distinguishing albino rabbits from those of different colors and visual characteristics important in rabbit showmanship.
