The Satinette mutation appeared on the Continent the late 1970’s. Originally it was thought that the Satinette mutation existed in all four classic series (Black, Agate, Brown and Isabel). However, it was discovered later that the Satinette mutation exists in the Isabel and Agate series only. The Satinette mutation is transmitted by sex-linked inheritance. The effect of the Satinette mutation is to totally prevent the presence of eumelanin black and to almost prevent completely the presence of phaeomelanin brown markings.
