A Series (Agouti locus, color pattern

A Series (Agouti locus, color pattern.)
Allele	Description
A	Normal agouti pattern. Banded (black and yellow) and ticked. White and light eye circles, under nostrils, belly, and underside of tail.
a^t	Black and Tan coat pattern. This allele gives the rabbit a white belly, black nonagouti on the dorsal surface, whitish eye circles, and tan on the foot pads, under the tail, and at the edge of the white belly.
a	Nonagouti. Solid black coat.
B Series (Black locus, color)
Allele	Description
B	Wild type, black eumelanin.
b	Replacement of black eumelanin with brown eumelanin.
Notes: Agouti brown rabbits are cinnamon colored, where nonagouti brown rabbits are solid brown in color.
C Series (Color locus, amount of color.)
Allele	Description
C	Normal pigmentation. Fully colored. Brown eyes.
c^chd	Yellow pigment is reduced to white. Blue-grey or marbled blue eyes.
c^chm	Black pigment reduced to sepia brown. Also called the sable gene. Color is shaded, typical sable when with non-agouti gene (a). Somewhat temperature-sensitive. Brown eyes.
c^chl	Further reduces black pigment to pale brown. Also may be called sable gene. Debatable whether it is present in U.S. rabbits.
c^h	Himalayan. Restricts all pigment to the extremities. This allele is temperature sensitive. Pink eyes
c	Albino. Eliminates all pigment. Pink eyes
Notes: Mutations in the C series reduces pigmentation. The superscripted H for the Himalayan gene indicates that it is dominant to the other alleles and the lower case c indicates it is recessive to the C, normal pigmentation. Pigment in the eye is also reduced by the alleles in this series. There is debate whether the C^chm gene exists or if the resulting colors are a homozygous combination of C^chd and C^chl.
D Series (Dilute/Density locus, arrangement)
Allele	Description
D	Normal pigmentation, black and yellow is intense.
d	Dilute pigmentation. Black to blue and red to yellow. Pigment granules are clumped; colors appear different.
Notes: The homozygous condition, dd, results in different pigmentation changes according to other alleles present. Black to a blue-gray, brown to lilac, or yellow to cream.

E Series (Extension locus)
Allele	Description
E^d	Reduces or eliminates the agouti band of phaeomelanin and darkens the belly. Black color is extended over the entire length of the hair shaft. There is debate as to whether this gene exists, or if the appearance is from a darker form of the E^s gene.
E^s	The Steel gene. Super extension of black on the agouti hair shatf, almost all black with very little yellow anding and/or ticking; belly an dother normally light areas of agouti are dark. A weaker version of E^d. Considered more codominant with E than E^d.
E	Normal gray. Normal extension of the black and yellow pigments.
e^j	Japanese brindling. Mosaic distribution of black and yellow pigmentation. Patches, bands, bars, or brindling of yellow and black. Can be diluted to Blue and Fawn, Lilac and Fawn, and Chocolate and Gold by the B and D series.
e	Fawn color. Coat is yellow with a white belly
En Series (English Spotting)
Allele	Description
En	English marking.
en	Self coloring.
Du Series (Dutch Spotting)
Allele	Description
Du	Self coloring.
du^d	Dark Dutch. Minimal amounts of white.
du^w	Light Dutch. Extensive white spotting.
There is debate whether the Dutch coat pattern is caused by the du^d and du^w alleles or a single recessive du allele. There is evidence in Dutch herds that favors a single du reccesive allele.
V Series (Vienna White, BEW)
Allele	Description
V	Wild Type.
v	Vienna White. All pigment is removed from the hair. Pigment is also removed from the anterior surface of the iris, giving it a blue appearance.
W Series (Wide Band)
Allele	Description
W	Normal agouti band.
w	Subterminal agouti band double in width.
Silvering
Allele	Description
Si	Normal
si	Silvering.
