Roan is a relatively new pattern, but is the result of a fairly old gene, the White Bellied gene, sometimes called the Anophthalmic, (Eyeless), White gene.
ONE copy of this gene gives Agouti animals, (those with cheek flashes, such as Golden), pure white belly fur, together with a light brindling of white hair in their top colour. TWO copies of this gene, (one inherited from each parent), produce a pure white hamster with no eyes - an Eyeless White.
When a Self-coloured animal, such as a Sable, has one copy of this gene, it too will have pure white belly fur, but the brindling effect apparent in Agouti animals is changed into an attractive "marbling". The head of the animal is coloured, but the colour decreases, (and white increases), from shoulders to tail root. Sable Roans are the commonest seen, but Cream or even Mink Roans are not unknown.
Due to the risk of producing eyeless youngsters, Roan animals must NEVER be
mated to another Roan. Mating to the equivalent solid coloured animal should
give a fifty: fifty mixture of Roans and Self coloured animals in the litter.
1. Overall Appearance: The Roan shall have the appearance of a white animal ticked with colour. The ticking shall be heavy around the head and give an evenly marbled appearance over the remainder of the top coat. The white areas shall be white to the roots. The coloured areas shall conform to the recognised coloured variety allowing for slight dilution.
2. The belly fur shall be marbled with colour
3. Eye Colour: As for the full coloured variety also ruby or red eye or eyes permissible.
4. Ear Colour : As for the full coloured variety also flesh or partly flesh
coloured ears permissible.
