It results in different colors and patterns and can affect any coats. The allele creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well. Two ...

Deeper colors are preferred; predominantly white coats are discouraged. Since Catahoula is a working dog, coat color is not a primary consideration. [1] [6]

The same gene that controls wiriness of hair also causes furnishings to be present (e.g. beard, moustache, eyebrows) [ 8 ] - compare the bearded collie , furnishings present, to the border collie , which ...
Great Danes also may carry the merle gene, which is part of the genetic makeup that creates the harlequin coloring. [35] The merle gene is an incomplete dominant, meaning only one copy of the gene is needed to show the merle coloring; two merle genes produce excessive white markings and many health issues such as deafness, blindness, or other ...
In 2018, a genetic study found that just prior to 1859 a broadly distributed European herding dog had given rise to the German Shepherd Dog, the French Berger Picard, and the five Italian herding breeds: the Bergamasco Shepherd, Cane Paratore, Lupino del Gigante, Pastore d'Oropa, and the Pastore della Lessinia e del Lagorai.
