Genes have locus's, which can have alleles as modifiers . The two pigments that combine to make colors in rabbits are Black/Brown (eumelanin) & Yellow (red - pheomelanin)
Waldorf is a wild colored Chestnut
He has Dominate alleles across his phenotype.
A- B- C-D-E-
at- Produces Tan's, Otters , and Martains
Black is the Dominate color in Rabbits , Chocolate is the recessive.
The B loci expresses the quality of eumelanin. Eumelanin can be exspressed as either Black or Brown, and their are many colors that are created depending on which of these is the base color. Their are also genes that mask or remove the ability for a hair folical to produce eumelanin, in these cases either no pigment(white) or onl pheomelanin(Yellow/Red) are exspressed.
T-Payne is a Black Self .
His Hairs are solid black
from Base to tip.
The Color Concentration Loci has four Alleles.
"C" Full color is Dominate,
"cchd" or "chd" which is Dark Chinchilla, this strips most of the pheomelanin (red/yellow) and it turns grey/white while leaving the eumelanin (black/chocolate) alone.
"cchl"or " chl" Light Chinchilla , strips the pheomelanin (red/yellow) and some of the eumelanin (black/chocolate) giving it a shaded appearance. It can also give the eumelanin a lightning effect turning it a sepia color.
"ch" Himalayan (or Californian) allele , is a temperature sensitive allele that leaves colors at only pointed tips . The parts of the rabbit espoused to the coldest temperatures have the richest darkest colors and the color intensity can change seasonally.
"c" is the most recessive . Two copies of "c" on this allele produce Red Eye Whites. Although "c" this is the most recessive gene, in some ways has the most dominate effect. When "cc" is expressed it prevents both pheomelanin and eumelanin from being exspressed, and this then masks all other Loci hiding the rabbits actual coat colors completely.

This loci has two Allele D- & dd . The D Loci, effects the Eumelanin of a rabbit on the B locus. A rabbit that has double recessive genes for dilution "dd", will make a Black Rabbit Blue, and a Chocolate Rabbit a Tan/Fawn color called " lilac" in rabbits.
D is dominate for no dilution or full Density of color,
d is recessive and Diluties the color .

This Alle modifies the bands on an Argouti Rabbit .
Ed dominate black. This is the most Dominate Gene on the E loci, it is more Dominate then Es.
This gene exspresses Full soild color at the B loci Eumelinin . It completly extendes the black bands on the Argouti hair shaft with wha ever color is present in B. Some Genetisists have theorized that a Double Steel coat can also present as Dominate black, but since the Ed marker has been reported as far back as the 1800's I am incuding it. I also wonder if my Broken black Buck may actually carry this gene along with E.
Es Steel , A Steel Coat the hait shaft is mostly black with a gold or White/silver Tip, tip color is depended on where the Rabbit can produce pheomelanin or not. A Gold Tipped Steel is a nomal presenting pheomelanin, a Silver tipped Steele is most likly a Chinchilla Rabbit at C. Double Steel will extend the pigment of the shafts on some rabbits to make a Agouti look like a self black.
E is the thrids most dominate gene , It exspresses Regular Extenstion, or normal expression of the colors at the A and B loci
ej Harlequin characterized by alternating patches of banding. These rabbits look Bringdled or patched, in te harliquen Breed, the Color is perfered to have a Perfectly Split face between the pheomelanin and eumelinin sides, with the opposite ear colored, and again the oposite front legs, Ideally the rabbit will have a clean checker board like pattern . Very Clean Harliquens with havea densly colored coat with clean patches but in co-domiante rabbits brindling and mudding of the patches is common. ej exspresses itseld in 2 base colors.
e Tort/ non-extension the oposite of the Steels with the light part of the Agouti hairs extended to the base. Non-extention strips out the eumelinin from the argouti coat and presents as a yellow/red soild colored rabbit, but it is common for these rabbits to still show the creamy/white underbelly that distinguises the Argouti.
A Tort is a Self colored rabbit at A, " aa" and it exspressed as a Reddish soild coat since the pheomelanin masks the Color at A, but they tend to exspress the eumelinin with darker points. silimar to the Hymilation points, their Nose, Ears, Feet and Tail will be shaded darker.
