Red Eyed Ivory (eeLglgpp or eedgdgpp)

Combining the Black Eyed Cream gene with any of the three grey genes, (Silver, Light or Dark Grey), will produce Black Eyed Ivory. Adding the Cinnamon gene to the mixture produces Red Eyed Ivory. The colour is comparatively rare, but is fairly easy to breed, now that two dominant forms of grey are available, since the other two genes, Cream and Cinnamon, are relatively common. The major difficulty is that if a breeder has a Red Eyed Ivory of unknown ancestory, (for example, from a pet shop), it can be difficult to breed on from reliably until it is ascertained precisely which grey gene is involved. The simplest way to determine this is to mate to a Red Eyed Cream, (or failing that, a Black Eyed Cream).

A Red Eyed Ivory produced by combining the dominant genes Silver Grey or Light Grey with Cream will, when mated to a Black Eyed or Red Eyed Cream, produce Ivory young in the litter, (together with some Creams). The young Creams, (and/ or Ivories), from this mating will normally have the eye colour, (red or black), of their Cream parent. The reason is that the Cinnamon gene, (giving red eyes), is recessive to "non Cinnamon", (which gives black eyes). The young all inherit a Cinnamon gene from their Red Eyed Ivory parent, so the eye colour depends on whether or not they inherit one from the Cream parent.

Since Dark Grey is recessive¸(and so has to be inherited from both parents), mating a Cream to a Red Eyed Ivory derived by combining Black Eyed Cream, Cinnamon and Dark Grey will only produce Cream young, (again, with the eye colour of the Cream parent).

To breed Red Eyed Ivory will require one of two strategies, in the absence of a like coloured mate. In both cases, the animal should be mated to Cream, (preferably Red Eyed), which takes care of at least one, (or two), of the "constituent" genes. Then only the "Grey" gene need be worried about.

For Ivories containing the Silver or Light Grey genes the situation is simple; it is sufficient to breed to Red Eyed Creams. Some of the young will inherit the Grey gene, and will be Red Eyed Ivory, others will not, and will be Red Eyed Cream. If a Black Eyed Cream is used, Black Eyed Creams and Black Eyed Ivories, both carrying Cinnamon, will be produced.

For the Red Eyed Ivories derived using Dark Grey, the youngsters from an Ivory - Red Eyed Cream mating will be Red Eyed Creams, carrying Dark Grey. Mating one of these back to it's Ivory parent will produce a litter of roughly half Red Eyed Ivories and half Red Eyed Creams. Alternatively, mating brother to sister will produce roughly three quarters Red Eyed Creams and one quarter Red Eyed Ivories. If a Black Eyed Cream is used, instead of a Red Eyed one, the young in the first generation will be Black Eyed Creams. Mating these back to their Red Eyed Ivory parent will be expected to produce equal proportions of Red Eyed Ivory, Black Eyed Ivory, Red Eyed Cream and Black Eyed Cream young. Mating brother to sister would be expected to produce Black Eyed Creams, Red Eyed Creams, Black Eyed Ivories and Red Eyed Ivories in the ratio 9:3:3:1, and so is not such a productive method of propogating the colour.
