Which term is used to describe a flat appearance of a rabbit's fur?

The term used to describe a flat appearance of a rabbit's fur is "Pepper and Salt." In the context of rabbit fur, this phrase often refers to a color pattern or texture where the coat has a mixture of dark and light hairs that create a flat, blended appearance. This is typically seen in certain breeds and can give the rabbit a more uniform look, lacking the defined stand of fur that characterizes other coat types.

The other options do not accurately describe a flat appearance of a rabbit's fur. "Poor Coat" generally refers to a rabbit's fur that is unhealthy or poorly maintained, lacking luster or density. "Peanut" usually refers to a specific color or pattern in rabbits rather than the texture of the fur. "Phenotype," on the other hand, is a broader term that refers to the observable physical traits of an organism, which can include but is not limited to fur texture and color. Thus, "Pepper and Salt" specifically captures the intended description of a flat fur appearance.
