Other names: Robert
Genetics: One copy of the wild-type h-locus allele, and one copy of the Essex gene (HroH). The Essex gene causes the colour to become paler than standard, so black becomes charcoal-grey, agouti looks almost sandy coloured, and so on.
Description: Full colour to run along the top of the rat; the darkest area being along the spine, becoming less intense down the sides of the animal. The gradual fading of colour continues until the belly itself is off-white, with no spotting or darker colour. When viewed from above, the fading effect should be symmetrical, having no clear demarcation. there should be no obvious patches of contrasting colour. Face Marking: A head spot is essential. This must be well defined and symmetrical. Long blazes are to be discouraged. A white nose tip is permissible.
Status: This marking is standardised in UK rat clubs with the name Essex
