The Fischer–Saller Scale, named for eugenicist Eugen Fischer and German anthropologist Karl Saller , is used in physical anthropology and medicine to determine the shades of hair color. The scale uses the following designations: [1] [2] [3] [4]
An agouti dog, also called wolf sable. In dogs, the agouti gene is associated with various coat colors and patterns. [10]The alleles at the A locus are related to the production of agouti-signaling protein (ASIP) and determine whether an animal expresses an agouti appearance and, by controlling the distribution of pigment in individual hairs, what type of agouti.
However, cats can also have double-layered coats out of two hair types in which the down hairs form the soft, insulating undercoat, and the guard hairs form the protective outer coat. [40] A typical cat coat exists of all three natural hair types, but due to the equal lengths of two of these hairs, the coat is still considered double-layered. [40]

However, the pervasive coat color among wild equids is dun, and researchers from Darwin to modern day consider dun to be the wildtype state. [29] [30] An older non-dun mutation was found in 2015 and named non-dun 1. It creates primitive markings but does not dilute the base color, and is co-dominant with the more common non-dun 2 but recessive ...
