How you think they get all that mutation??? It's from mixing different mutations together. None of these mutations exist out in the wild. Except for Albinos at times, but they usually never make it out in the wild. For example, if you have a Lutino Male Cockatiel and you mix with a Basic Color Female like Cinnamon, Pearl, or Grey. All your baby Girls will be Lutinos while the baby boys will be poor pieds depending on the mother's coloring. Or sometimes depending on the hidden gene on the parents. IF you mix a Lutino to a Lutino, all their babies will mainly be Lutinos again that certain factor MAY pop out depending on the hidden genes. BUT a word of caution when you mix mutations, for example, Lutino to Lutino, Albino to Albino, the babies tend to have more health issues and their head tend to go bald worse and worse every time you mix the new generation again with the same coloring. To the point from the back of the crown to the neck will be all bald. So you MUST be careful and read up on your genetics before trying to mix different mutations together. I used to breed mine for certain coloring. I did a lot of genetics research....
