The violet Quaker parrot mutation was produced by selective breeding. selective breeding is a process in which breeders carefully choose which birds to breed based on certain desired traits. The violet mutation is a result of a recessive gene, which means that it must be inherited from both parents in order to be expressed. To produce violet offspring, breeding two birds that possess the violet gene will be undertaken. The violet Quaker parrot mutation is one of the rarest mutations, which makes them highly sought after by bird enthusiasts. It's also important to note that selective breeding can also lead to potential health problems and genetic disorders. It's recommended to always consult with an avian veterinarian or an avian expert to ensure the bird is getting the right nutrition and care.
