Basic Color Genetics
The five base Alle's that effects the base coat color of the Domestic rabbit.( DISCRIPE THE BASIC DEFEINTION OF EACH, LINK TO NEW PAGE FOR INDEPTH DISCUSSION.)
A- Agouti
The Agouti gene has three variable Alles. Agouti is the most dominate followed by Tan , and then Self is the most recessive.
B-Black/Brown
The B marker has 2 Alle's , Black is Dominate to Brown.
C-Color Coverage
there are four alles on the color concentration marker. Full Color, Chinchilla, Shaded/light chinchilla, Himalayan, and Albino.
D-Density
Density Gene has two Alle's, Full Density is dominate, and Dilute is recessive. The representation of The Dominate full Darkness marker is usually defined as " D". While the Dilute , is a higher "brightness" marker is usually defined as "d". This gene can be thought of like the brightness slider under the hue/saturation adjuster in photoshop. Your default image (D) is set to 0, while the Dilute is akin to +50 brightness.
example :
E-Extension
The Extension gene has five separate markers that control the extend of the band of an Agouti rabbit. Ed dominate black the rabbit will appear self as it will extend the color at B to entire hair follicle, Es steel is the second most dominate color, this extends the color at the B loci almost to the tip on an agouti rabbit, so the follicle will be soil 3/4 of the way to the tip with just the tip showing a red/yellow/white coloring. , E-regular extension, this will preset the hair as it is, and Agouti rabbit will have banded color along the hair shaft, and a self or tan rabbit will have a soil hair coloration. ej-Japanese harliqe is a co-dominate recessive gene that expresses patches of alternating color, or Bridling on Agouti coats. ee-is non-extention, it is the oposite of dominate black and hide the color at B on Agouti rabbit extending the tip color to the base . and blocking out all Eumelnion.
