Vienna-marked rabbits

What is the Vienna gene?
The Vienna gene is responsible for creating blue-eyed white (BEW) rabbits with bright blue cornflower eyes. A rabbit with a single Vienna gene can be Vienna-marked (VM) or a Vienna carrier (VC). Vienna-marked rabbits often have Dutch-like markings with partial heterochromia in one or both eyes. A Vienna carrier will have no outward markings of the gene.
