Although there are many kinds of chinchilla colors, caution is needed to be taken into account in breeding. Not all the color of the chinchilla can mate with each other. Some specific colors of chinchilla once mating breeding, the death rate will be very high, female and fetus will be life-threatening, this is known as the lethal gene collocation. So, which genes could be lethal when combined?
Velvet and velvet in chinchilla gene
Two chinchillas with velvet genes are advised not to breed. Generally, the colors of chinchilla that belong to velvet gene are velvet black, velvet pink white, velvet silver spot, velvet purple gray, velvet coffee. Please do not mate and breed with each other. It is a lethal combination.
2. White and white in chinchilla
Two chinchillas with white genes are advised not to breed. Generally, the color of chinchilla that belongs to white gene is silver spot, pink white, velvet pink white, velvet silver spot and gold spot. Please do not mate and breed with each other. It is a lethal combination.
3. Chinchilla with silver spots or velvet spots
If the color is silver spot or velvet silver spot, it is often difficult to distinguish which gene combination it is from their appearance, because after several times of reproduction, a chinchilla may have a mixed color composed of concentrated monochromatic genes, which requires us to know the parents of this chinchilla, and sometimes even the colors of its grandparents.
Do not think that the probability of death is relatively low, there is a fluke mentality. This is because the lethal gene combination is likely to cause stillbirth in the female chinchilla, especially when the female has given birth to one or two kittens, the stillbirth appears in her body. However, we do not know that the female chinchilla is just weak after birth, which is enough to kill the female chinchilla. And it is very likely that early abortion, or other abnormalities in pregnancy, not only the fetus is not protected, the female dragon cat will also be fatally at risk. Even if it happens that this production is safe, who can guarantee that there will be no danger next time?
Therefore, we should first understand their genes when pairing chinchillas, especially those that need two or more genes of different colors to breed, such as coffee or powdery white. We need to split the gene into monochromatic genes and match them according to the type of monochromatic genes their parents or grandparents are.
