The Vienna marking gene.

 The Vienna marking.

The Vienna marking (v or without the marking V).

 The Vienna marking is a white splotch on the forehead and one on the nose which is typically wanted on "non-brokens", because it can cause a half color mark on the nose which is a DQ for showing. The Vienna marking is also a DQ for showing because it is not a qualified white marking (a qualifying one for example are the white splotches on brokens, I could go on and on about the showing needs, wants, etc... but I think I'm saving that for other posts) on your rabbit. The Vienna marking is neither dominant or recessive, it is true that to get the full marking you would have to have two of the genes vv but when the bunny only carries the gene (Vv) than it can possibly "pop" which makes it not recessive, when the Vienna gene "pops" it means that it shows part of the marking. The Vienna marking is also an unwanted marking for showing but is also a very wanted gene/marking for pets (it makes them look extra cute), so you can't go bad either way (as long as you don't show your bunny with a Vienna marking and just keep it as a pet). But beyond all the bunnies make cute pets with it but for showing you want one without so either way are both pros and not cons in my view.

Below are some punnett squares for breeding VV & vv, VV & Vv, Vv &Vv, and Vv & vv.

When parent 1 has VV genes and parent 2 has vv genes; 100% of offspring will be Vv.

 

 When parent 1 has VV genes and parent 2 has Vv genes; 50% of offspring will be Vv and 50% will be VV.


When parent 1 has Vv genes and parent 2 has Vv genes; 50% of offspring will be Vv, 25% of offspring will be VV, and 25% of offspring will be vv.

When parent 1 has VV genes and parent 2 has vv genes; 50% of offspring will be Vv and 50% of offspring will be vv.

The B_ gene set.

Gene set B_  The B_ gene set controls weather the base color is brown or black. The Black gene.  The black gene (B_). The black gene means black is the base color of the bunny's fur coat, that means that any color that is black changed black like blue (looks dark grey colored) has the base black colored gene. Variations of this gene: B_ & Bb. The Brown gene.   The brown gene (bb). The brown gene means chocolate is the base color of the bunny's fur coat, that means that any color that is chocolate or lighter or somewhat changed brown colored such as orange has the base chocolate (brown) colored gene. The only variation of this gene to show is bb. Here's some punnet squares for the variations these genes could have as out comes.  Here is if parent 1 with BB genes had offspring with parent 2 who had bb genes, all offspring would be Bb (black colored and carry the recessive b gene).   Here is if parent 1 with Bb genes had offspring with parent 2 who had Bb ...

The C_ gene set.

-
Gene set C_ The C_ gene set is one of the most complex gene sets of the five, it's called the color gene and basically controls how much pigment your bunny has in its fur.  Note: As in other posts I'll order the genes from the most dominant genes to the most recessive genes.  The full color gene (C_). This gene is pretty simple (it is the name) it's just the full color pigment in your rabbit's fur.  Variations of this gene includes: C cchd, Ccchl, Cch, & Cc. The Chinchilla dark gene ( cchd).  This gene shares dominance with the chinchilla light gene (cchl) or co-dominance. This gene shows the Agouti pattern but lightens any yellow or off white to white as well as doesn't let all the color pigment but most show, it also some times makes rabbits with blue eyes.  Variations of this gene includes: cchd, cchdcchl, cchdch, & cchdcc. The C hinchilla light gene (cchl).  This gene will not let the Agouti gene show and will let most of the darker pigment ...
