Rabbit Genetics: Vienna & Broken

The V Locus:

There are two genes in the V Locus. The most dominant is “V” and the most recessive is “v”.

~ Non-Vienna
“V” is called the Non-Vienna gene. This gene can be homozygous or heterozygous. This gene creates the normal color that is seen in all colors except Blue-Eyed-White (BEW). Some of the colors that have the Non-Vienna gene are as follows:

All varieties except Blue-Eyed-White (BEW).

Non-Vienna can carry Vienna. Non-Viennas that carry the Vienna gene are called Vienna Carries (VC).

~ Vienna
“v” is called the Vienna gene. This gene can only be homozygous. It cannot carry any other gene as a recessive gene cannot carry a dominant gene. This gene masks all other genes leaving the coat white and turning the eyes blue. Some of the colors that have the Vienna gene are:

Blue-Eyed-White (BEW)

~ Incompletely Dominant (Vienna Marked, Sports)
When the Non-Vienna gene is paired with the Vienna gene the animals will often have white markings with their regular color. Some of the time the markings are similar to Dutch markings but, sometimes they just have white spots in different areas. The reason for this is because the Vienna gene is incompletely recessive to the Non-Vienna gene so, that when it is paired with the Non-Vienna gene sports are the result. Vienna Marked animals or Sports have the following genotype, “Vv”. Sometimes these sports will not show any sport markings but, a lot of the time they do.

The Broken (En) Locus:

There are 2 genes in this locus. The most dominant is “En” and the most recessive is “en”.

The broken genetics are incompletely dominant. To get a normal broken pattern, you need one broken (En) gene and one solid (en) gene. If you have two broken genes, then it is what is referred to as a Charlie. A Charlie pattern broken was named after Charlie Chaplain because they often have a little Charlie Chaplain moustache, and they often only have a small stripe of color down the center of their back. A Charlie a Charlie you need two broken (EnEn) genes. To get a solid you need two solid (enen) genes.

If a Charlie is bred to a solid you can only get brokens. The reason is because the Charlie is “EnEn” and the solid is “enen”. Brokens need one broken gene and one solid gene (Enen). A Charlie is not possible out of a solid x Charlie breeding because a solid needs 2 broken genes (EnEn) and the solid does not carry a broken gene. A solid is also not possible because a solid needs two solid genes (enen) and a Charlie does not carry a solid gene.

If a broken is bred to a solid you can get brokens and solids. You cannot get any charlies because both parents have to have a broken gene to be able to produce a Charlie. You can get solids because the broken carries one solid gene and one broken gene. The broken will have to pass the solid gene and the solid will have to pass one solid gene in order to create a solid. To get a broken the broken will have to contribute a broken gene and the solid will have to give one solid gene.

If a broken is bred to a broken you can get brokens, solids, and charlies. To get a broken one of the brokens has to give one broken gene and the other broken has to give a solid gene. To get a solid each broken has to give one solid gene. To get a Charlie each broken has to give a broken gene.

If you breed a charlie to a broken, you should get 50/50 charlie/broken. You are much more likely to get more charlies than brokens. To get a broken the broken has to give a solid gene and the Charlie has to give a broken gene.

If two charlies are bred together you can get only charlies. Both of the charlies have two broken genes and thus can only produce charlies and cannot produce brokens or solids.
