The standard of Devil- / Marten Rat
Die American Fancy Rat and Mouse Associations and the National Fancy Rat Society (NFRS) describe in their standards or Devils. Martens, as they are called in English-speaking countries, as follows. The color of the body should be comparable with a pencil hardness HB, in adult animals, the color may be slightly faded. Light color stains can be expected. The fur on the face should at the base of whiskers, be lightened over the eyes and behind the ears. The belly has a slightly paler shade of gray than the top. The color of the feet should correspond to the top. When errors are rust, white toes or spots and darker points at the nose, viewed the tail and feet. The eyes should be pink.
The NFRS also describes nor the agouti version of the Devils / Marten, which is referred to in the UK as Silver Agouti. The color is a mix of medium gray banding (Ticking) over a pale ivory ground, without any hint of blue or brown undertones. The harness should be the darkest along the back and fade over the sides to a pale ivory belly. Even with these animals' hair should be in the face at the base of whiskers, be lightened over the eyes and behind the ears. Apply the same mistakes as the the Devils / Marten.
The history of the Devil- / Marten Rat
The first Devils were 2008 discovered by René Bastiaans in the Netherlands. They came from German laboratory strains and RED were initially for "Red Eyed Devil" called, since there were only Devil with red eyes at the time. 2010 the animals were imported into the UK and there as Marten (engl. For "marten") designated. Meanwhile, black-eyed Devils could be crossbreeding of the UK Black Eyed gene pulled.
Genetics of Devil- / Marten Rat
the genetics, which is the destruction the Devil-Shade, was as so often with new varieties initially unknown. Initially it was assumed, that lying on a different locus Modifier the expression of alleles of the locus C [also C, c and c(h)] affected (compare farbrattengenetik.de.tl).
Meanwhile, it is assumed, that there is a lying on the C-locus allele in the party responsible for Devil shading Genetics. This allele is c(m) designated. Further lying on the C locus alleles are C or for standard. Non-Albino, c for albino and c(h) Himalaya (homozygot Siam).
Das Devil- or. Marten allele is recessive to C, dominant over c and incompletely dominant over c(h).
This has the following genotype and phenotype in combination with the Devil- / Marten allele:
cc(m) - "Albino" Devil ohne points
c(m)c(m) - homozygoter Devil ohne points
c(h)c(m) - Himalaya Devil mit Points
For Black Eyed Devils the UK black eyed allele in a homozygous form is also required.
From the considerations of genetics underlying suggests, that the shading Devil with all sorts of colors, drawings, Coat types and body types can be combined. However, it should be noted, that have been reported no Devil outfits with Red Eye Dilute or pink Eyey Dilute, but what may be because, that the animals are difficult to detect. DarauAus the possible combinations result phenotypes, which significantly differ from the standards of AFRMA and NFRS. Including Devils with drawings are of course possible.
