More Advanced Color Genetics:
BROKEN LOCI
- En-broken
The broken Pattern is dominate to solid. Rabbits with two Broken Geans are called Charlies and should be only very carefully bred. The Broken gene when homozygous (doubled up) carries a 70% probability of producing a Rabbit with megacolon, a digestive tract disorder.
Vienna
- V-Vienna
Vienna is most frequently known for Blue eye white as two copies of "vm" will produce a solid white rabbit with blue eyes. Vienna is a co-dominate gene, and a "Vmvm" rabbit is a Vienna carrier, in this case some random white markings can bleed through including the brilliant blue eye color in one , part of or both eyes.
Wideband
- W-Wideband
Wide band is a trait modifier gene that will effect Agouti based rabbits. the wide band gene extends the band coverage, primarily on Chestnuts, Reds, and Chinchillas. a chestnut will have a larger area of Pheomelanin showing on the coat and less white, and more red/yellow on it's belly(Coppers), a Chinchilla will have more white on it's coat and more white on it's belly, and a red will have a more solid red belly extended from it's back. Wide band high rufus reds and chestnuts are the most sought after to improve color in a new Zealand red program.
Dutch
- Du-Dutch
Silver
- Si-Silver
Silver gene is indicated by full solid white hairs from root to tip evenly inter mixed with the body color hairs .
Modifiers
Modifiers are not gene on their own but the extent of coverage that rabbit is presenting.
Intensity of Red
The intensity of Red is a gene modifier that controls how saturated the Pheomelanin is in a rabbits coat. We refer to this as Rufus. A rabbit with very little intensity can look almost like a dirty white, while a Rabbit with extremely high Rufus can present as a deep mahogany maroon color. Rufus can also play a role in the quality of other coat colors becuse it turns up the saturation on pigments in the hair follicle. example: a truly rich inky black rabbit has a high Rufus, while a low Rufus Rabbit will appear a duller more charcoal black.
Extent of Broken Pattern
- "Charlie "
- Broken
- Blanket
- Booted
Codominant genes:
Genes that are partially dominate even when recessive. and Genes that present more intense when doubled up ie produce "phantom" colors , colors that present as something they arn't.
- ej- Harlequin
Harlequin *ej* can bleed through on self "aa, Eej " Chinchilla "A, chd, Eej" Chestnut " A, Eej " .

"EsEs" or "Ese" can present as Black
- Ed -Dominate Black
- Vm - Vienna
