All right, I am new to this, so please bear with me. :)

So...the basic modifiers. They are:

A B C D E W V En

Each has its own purpose. I will be explaining their uses.

Before I explain, I want to clarify something. There are only 2 colors. Black and Chocolate. Every other variety is a variance of these two colors.

So, onto the modifiers!

The A modifier is responsible for the patterns.

A= Agouti, which is the most dominant
at= Tan, which dominates over self but is recessive to Agouti
aa= Self, recessive to all of the above

The B modifier is responsible for the colors.

B= Black, dominant in this case
b= Chocolate, which is fully recessive. It requires a bb to actually see chocolate.

The D modifier is responsible for the richness of color.

D= Intense
d= Dilute

The C modifier is responsible for the variations of the pattern.

(The hair shaft has several layers of colors on it. I will be using the layers to explain the differences between the first three colors)
C= Full Color, has 4 layers of black and 3 layers of yellow
Cchd= dark Chinchilla, has 4 layers of black and 1 layer of yellow
Cchl= light Chinchilla, has 2 blacks (which appear brown) and no yellow (Shaded)
c h= Himalayan, which obscures color developement except on the points (ears, feet, nose, and tail)
c= Albino, which covers their original color. It is still there, you just can't see it!

The order in which you see these variations of color are occording to domination. Full color is the most dominant, so forth.

The E modifier is responsible for the pigment extension.

Es= Steel, most dominant.
E= Normal, has seemingly "no effect"
ej= Japanese, all tricolors contain this gene.
e= Non Extensions
En= short for "English". Is responsible for brokens.

There are variations to the En gene. Charlies, for example, are dominant EN,EN. Selfs are en,en. Regularly marked brokens are En,en.

The W modifier is responsible for wide band.

W= dominant
w= recessive

The wide band effect widens the intermediate agouti band almost double, and colors the belly and trim points. Selfs are not affected by this gene.

The V gene. I think you people are smart enough to have guessed what it is. No? It's the Vienna gene.

The hierarchy is simple.

V= dominant
v= Recessive

The Blue eyed white has v,v. The vienna marked rabbit (looks like a dutch) is V,v. All solid and agouti varieties have the dominant V,V.

Hallelujah! You survived! :D


I got this information from the ARBA book Raising Better Rabbits & Cavies.

Thanks for reading!

:thankyou:


Now if only I could look at random rabbit breeds and figure out their codes and understand it.... :?

Don't go by breeds, but by specific colors, for the most part, all genetic genotype codes are the same across breeds. Even if the name is different, there is still a general genetic name for what color you are looking at.
