Extention Gene Es - E - ej - e
The E/e gene controls whether the basic colour on the rabbit (black, blue, chocolate, or lilac) is extended all of the way to the end of the hair shaft or whether the basic colour stops and another finishes the hair shaft. The E series very simply governs the distribution of black (or what ever colour is being displayed in its place ie blue, choc, lilac)
Es- A steel rabbit (more than the normal amount of black).“steel,” which is symbolized by Es. It’s a variant on the extension gene that has a surprising twist. Usually, the gene that is found in nature is the dominant variety. But with the steel gene, it is actually dominant over the “E” full extension gene found in nature. You need only look for steeling in full-extension animals: black, blue, chocolate, lilac,

E-normal distribution as in self, agouti or otter/ marten. When a rabbit has full extension, it tends to look the same colour all over, such as with a blue rabbit, in short, the colour fully extends to the end of the hair shaft.
ej- Japanese brindling creating a striped/ block effect The ‘j’ stands for Japanese brindling”. When you see ej think “Harlequin” or “tricoloured”. (Japanese was the original name for harlequin and is still the name of a colour group in the harlequin breed.) The ej gene creates the colour groups Japanese, magpie, and tri-coloured. When a rabbit has a harlequin genotype but not clear harlie markings, this is called brindle. In technical terms, the ej gene segregates the dark brown and yellow pigments, putting them on separate hair shafts. The ej gene only works properly on rabbits that have the agouti gene.

e- restriction to points in self (sooty fawn, seal point ect), near removal in agouti (orange/ fawn) The (e) is a non-extension the rabbit colour on the hair shaft and takes on a shaded look since the shorter hairs on the belly, guard hairs, feet and muzzle get only the basic color (they are not long enough to get the other colour that finishes off the longer hairs).
