 //"Worauf hier noch besonders hingewiesen sei, das ist die Tatsache, daß es bis Anfang der neunziger Jahre des letzten Jahrhunderts beim [[:domestikation|domestizierten]] Kaninchen nur zwei reine// [nicht wildfarbige] //Farben gab, weiß und schwarz, entsprechend unseren primären Mutationstypen. Es gab weder ein reines [[haarfarbe_mlph|Blau]], wie es das heutige Blaue Wiener besitzt, noch ein reines [[haarfarbe_tyrp1|Braun]], wie beim Havanna, usw. Alle diese Farben waren eben noch kombiniert mit der Wildfarbigkeit, der zonenweisen Anordnung des Pigmentes im Rückenfell und der weißen Bauchseite."//((Nachtsheim, H. (1929).

 **Otterfarbige** Kaninchen wurden 1887 in England entdeckt, vier Jahre nachdem //"auf einer bis dahin von Kaninchen unbewohnten Insel drei Kaninchenrassen, nämlich Schwarzsilber, Holländerkaninchen in unbekannten Fellfarben und fahlblaue (blauwildfarbige?) Tiere"// ausgesetzt wurden.((Niehaus, H. 1987. Unsere Kaninchenrassen. Band II: Rassebeschreibungen. Reutlingen: Oertel + Spörer. ISBN: 3-88627-054-8.))(S. 155)\\

 Castle //et al//., 1909((Castle, W. E., Walter, H. E., Mullenix, R. C., & Cobb, S. 1909. Studies of inheritance in rabbits. Carnegie Institution of Washington. Publication no. 114.)) (Wildfarbig, einfarbig)
+//"Factor **G.**\\ This factor is again one which has been extensively studied. Its presence has been demonstrated in the mouse, rabbit, cavy, in the brown rat, and without any doubt it exists also in the hamster, the squirrel, in the hare and the fieldvole, as black individuals of all those animals are occasionally met with. When this factor G is absent from a germ, which contains all the other factors, A, B, C, D, E, F and H, but not I, the animal resulting from is black. Thus differ black and agouti cavies, mice, rats and rabbits only in the presence and absence of this factor. Black and agouti individuals of 'Mus rattus' do not differ in this way, it seems from the experiments of Morgan that in black 'Mus rattus' G is present, and that here the agouti colour is modified by the action of an additional factor, not present in the agouti animals. Some black rabbits seem to possess this same factor.\\
+[…] Matings between animals with and without the factor G have been made in large numbers with cavies by Miss SOLLAS and CASTLE, with rabbits by CASTLE, PUNNETT and HURST."//((Hagedoorn, A. L.

+//"Factor **O.**\\
+This factor has been studied by HURST. It is know only in the rabbit, at least, it has only been studied in that animal. Its presence makes an otherwisely black animal "Black and tan", that is, with a coat, black, with the exception of those parts which in an agouti animal are lightest, a spot behind the ear, rings around the eyes, the throat, belly and legs, which parts are mostly yellow. Otherwisely blue animals with this factor become blue and tan, the markings being much lighter yellow than in the black and tan. The relation of black and tan to agouti has, for as far as I know, not yet been studied, and it is therefore impossible to state wheter this factor is or is not present in the wild rabbit. It is well known that black and tan markings occur in certain varieties of dogs, goats, donkeys, and possibly cows."//((Hagedoorn, A. L. (1912).
