The standard grey chinchilla is the natural and original colour of the chinchilla. All other colours are mutations which have appeared in the herds of domestic chinchilla breeders, and perpetuated. Here are a few examples of the more common colour mutation croses and the percentage of offspring that will carry or exhibit the various colors: Standard/Standard 100% Standard Standard/Blond 100% Beige (heterocygot) Standard/White 25% Standard 25% White 50% Mosaic White/White 25% Standard 50% White 25% Lethal-Factor * Beige/Black Velvet 25% Standard 25% Beige 25% Black Velvet 25% TOV Beige White/Black Velvet 25% Standard 25% White 25% Black Velvet 25% Mosaic Standard/Black Velvet 50% Standard 50% Black Velvet White, Beige, Black Velvet/Ebony, Saphir, Violet 50% Standard (carrier) 50% White, Beige, Black Velvet (carrier) Standard/Ebony heterozygot (Saphir, Violet) 50% Standard Ebony (Saphir, Violet)-carrier 50% Ebony heterocygot TOV Violet (Saphir, Ebony)/Violet (Saphir, Ebony) 50% Violet 50% TOV Violet Standard/Ebony homocygot 100% Ebony heterocygot Ebony/Ebony 100% Ebony Beige/Beige 25% Standard 50% Beige (heterocygot) 25% Beige (homocygot) Black Velvet/Black Velvet 25% Standard 50% Black Velvet 25% Lethal-Factor* Saphir/Saphir 100% Saphir Violet/Violet 100% Violet Ebony/Saphir 50% Standard (carrier) 50% Ebony heterocygot (carrier) Ebony/Violet 100% Standard (carrier) White/Beige 25% Standard 25% White/Silver-Mosaic 25% Beige 25% Pink White TOV Violet (Saphir, Ebony)/TOV Violet (Saphir, Ebony) 25% Violet 50% TOV Violet 25% Lethal-Factor* Saphir/Violet 100% Standard (carrier)   * Lethal-Factor means that there will be no offspring Carriers are chins which have the "colorgene" of their parents. If they are put together with another carrier this color will become dominante again. For example: If you have two standards which are both violet-carrier then they will produce violets. There are many more possibilities than can appear by breeding or by chance. But the main thing always is to get healthy babies.
