B Locus
B > b

Eumelanin pigment.

BB, Bb = black
bb = liver

──────────────────────────────────────────────────────────────────────────────────

D Locus
D > d

──────────────────────────────────────────────────────────────────────────────────

Dilution.

Black ➜ Blue
Liver ➜ Isabella

DD or Dd = dense
dd = dilute

Co Locus
Co > co

Cocoa/Co Locus is only found in French Bulldogs! The effect primarily is seen on black based dogs, modified to turn the color called "Cocoa", a much deeper brown but still retaining the dark leathers and including the same eye-range as liver! It can be diluted to Lilac, a grey-brown type color with the typical diluted eye range and leathers diluted as well.

Supposedly the Cocoa/Co Locus does also effect Liver, however few or no photos have been able to be visually confirmable. Supposedly the coat appears like a warmer and more saturated shade of liver and may be referred to as "New Shade". Diluted liver-based cocoa is unconfirmed entirely. Due to this the colors have not been pictured here.

In order to show Cocoa modification, the dog must be homozygous.

Black ➜ Cocoa
Blue ➜ Lilac
Liver ➜ New Shade
Isabella ➜ ???

Coco or CoCo = Non Cocoa
coco = Cocoa

Tan Ranges

CNV > cnv and I > i

──────────────────────────────────────────────────────────────────────────────────

Red or rather "Tan" in dogs varies wildly, but are located in a large amount of breeds! When it comes to Tan, it is always going to be present underneath black, with the leathers and eyecolor hinging entirely on what type of black is present, and is NOT effected by the same gene as black dilution! Tan, Fawn, and Gold are all the same color- with that being the base unaltered color any dog can appear as.

What has been termed "Saturation" has barely been tested within that of breeds of poodles. Currently it has been separated from that of Intensity/Inhibitor as the dogs that were tested involving those colors do not show any reds in their genepool. CNV is the involved locus, and it has been confirmed homozygous dogs tend to be deeper colors than that of heterozygous dogs.

Intensity (aka Inhibitor) was previously thought to be found on the C Locus, of which is directly connected to albinism. It has actually been found in recent years to be a false assumption! Now found to be completely separated after the finding of dogs with markings like Colorpoint Cats, Intensity (I locus) has been confirmed how dogs gain white and near white colorations completely separate from black dilution! The color still varies but cream is known to be at least heterozygous and white or off-white (titled here "Ivory") are homozygous.

Realistically, the color of the darker reds is likely polygenic, but until more information is found, this is the most recent findings of how these colors function. Currently we don't know how these genes interact with one another as they typically are not found in the same breeds, nor are breed together.
