German Shepherd Coat Color Genetics
These loci control various traits - like coat length, ear type, and color. Color is controlled by multiple loci including: A (Agouti) locus K (Dominant Black) locus E (Extension) locus B (Brown) locus D (Dilution) locus S (White spotting) locus Now, when it comes to the German Shepherd dog coat genetics, the above loci play very significant. The intensity coat color gene variant causes an extreme dilution of phaeomelanin (red or yellow pigment), resulting in a cream to white coat in dogs.

Those are the standard and recognized colors by the SV. The SV standard, originally set up by Max von Stephanitz the creator of the German Shepherd, is the standard on to which all responsible breeders abide by. There are.
How to Predict My German Shepherd Puppy's Color? German Shepherd puppy color prediction is possible as coat color is all down to genetics. German Shepherds present as specific shades because they have the genes for those colors. At the same time, they may contain genes for other colors, but these may be recessive.

A White GSD carries genes for normal coat colors, but a separate gene on a separate locus can mask the normal coat color and make the entire dog white. It is NOT true that thre is "a lot of inbreeding" in them, nor is it a mutation. German Shepherds are a beloved breed, known for their intelligence, loyalty, and striking appearance.
While many envision the classic black and tan coat when they think of a German Shepherd, these dogs actually come in a wide range of colors and patterns. Understanding these variations not only adds to the appreciation of this breed but also informs potential owners about the genetics and care. Discover all German shepherd colors from classic black and tan to rare sable, bi-color, and white variations.

Complete guide to coat genetics and patterns. Understanding the genetic basis of German Shepherd colors requires knowledge of the genes responsible for coat pigmentation. The main genes involved include the Agouti gene, which determines the pattern of pigmentation, and the Melanocortin 1 Receptor gene, or MC1R, which controls the distribution and intensity of the pigment.
His 1989 book GENETICS OF THE DOG, his 1992 book PRACTICAL GENETICS FOR DOG BREEDERS, and his 1991 book THE GERMAN SHEPHERD DOG, A GENETIC HISTORY are great references. He does an excellent job of explaining the cases where the data is unclear or contradictory. There seems to be 11 major gene locations that determine the color and pattern of a dog.
