Dog Color Liver

Liver is a color name for a kind of brown, first recorded as such in English in 1686. [2] It may refer to the color of the organ. In particular, Liver describes a dark brown color in the coats of dogs and horses.

What Causes Liver Coloring in Dogs? The liver color in dogs is caused by a genetic mutation that dilutes black pigment into a brownish-red shade. All dogs have two primary pigments that make up their coat color: eumelanin and phaeomelanin. Eumelanin produces black and brown tones, while phaeomelanin produces red and yellow tones.

Dog Coat Colour Genetics

The liver color is the result of a recessive dilution gene that. The Liver Gene The liver gene occurs on the B locus, and causes a brownish colour. It's recessive, so b is liver and B is non-liver, and in order for a dog to be liver it must have the genotype bb.

This means that a liver puppy can be born from black parents if both are carriers of the liver allele (i.e. if both are Bb then at least one pup in four will be bb - see the Breeding page). The.

In dogs, the Liver color is caused by dilution of the eumelanin (black) pigment by the B locus. The gene that causes Liver is recessive, so a BB or Bb dog has normal black pigment. Only a bb dog is Liver.

There are several different recessive b genes, but they all turn the coat brown. A dog must be homozygous for brown (b/b) and able to produce eumelanin (at least one copy of the E allele at MC1R) in order to express a liver/brown/chocolate phenotype. Canine Coat Color Genetics, Part 2 Liver and Blue Coat Colors Fred Lanting, All-Breed Judge, SAAB, Sieger/Schutzhund In Part One, I mentioned that a recently discovered chromosome location called the K locus, which has genetic information on (control over) such coat-color expressions as solid black, brindle, and part of the reason for tan markings.

I also mentioned the "agouti" genes found. This dilutes the black color pigment into a brown color. This mutated gene is known as the "b" allele.

When a dog is homozygous for the mutation, meaning he has two copies of the recessive allele (b/b), all black pigment appears brown. This color can also be referred to as liver or chocolate. The homozygous liver sable GSD condition can happen, and would produce a less distinct contrast of overlay to the tan ground color.

Much of the appearance would depend on what genes are at the C, E, A, and perhaps others unidentified loci. It can be mistaken for a fawn-colored mixed-breed, but incidence of this might be very rare. The color liver (dogs) with hexadecimal color code #b86d29 is a shade of orange.

In the RGB color model #b86d29 is composed of 72.16% red, 42.75% green and 16.08% blue. A liver color in dogs is caused by a dilution of the black pigment. Basically, this color is best described as dark brown, or in some breeds, it is called chocolate brown.
