5.2 Secondary Mutations
In this final chapter of our tutorial we will list secondary mutations that are a combination of two or more primary mutations. Knowing which primary mutations combine together to create a particular secondary mutation is important to calculate genetic outcome using both the Punnett squares method and the genetic calculator. For example, albino is a combination of Blue and Ino, when both mutations are visually present together we get a visual albino. Following is a list of common names for ringnecks and the primary mutations that are involved in each. Please note that most of these names and combinations are common to budgerigars, lovebirds and some other species.
