At Essex is a drawing, which can occur on all colors. Essex rats have a characteristic gradient, in which the most intense staining along the spine occurs. The color is then lighter towards the belly. Furthermore, the animals have a Head Spot, which can partly take the form of a blaze.
The first Essex were 1996 Sheila Sowter found in a pet shop. First, the animals were as "Roberts Rats" designated.
The standard of Essex rat
Essex is recognized in all standard colors, However, the Essex effect can keep, that even the color of the top brightened appear. The darkest area is located along the spine and is brighter towards the underside. The gradual fading of color continues to the belly, which should be off-white. Seen from above, the effect of bleaching should be symmetrical and without bounds. The effect should be observed on the legs and feet. There should be no discernible trace of a contrasting color. A Head Spot is essential. He must be well defined, centrally placed and be symmetrical.
The genetics of Essex rat
The genetic background, leads to Essex drawing, is not yet fully understood. Man believed, that it is a lethal dominant allele at the locus H, with the H(ro) referred to as (by by Sheila Sowter, N.F.R.S.).
If you mated with self Essex, obtained Essex and elf. A mating with Hooded results Capped or. Baldie. The effect of the gradual fading of the clearest on dark colors with black eyes (Agouti, Cinnamon, Russian Blue etc.), the effect is less pronounced in red- or pinkäugigen animals and hardly visible on Cinnamon Pearl.
