The following charts are printed here merely as a reference for calculating one mutation at a time and should not be confused with the charting
methods used in COCKATIEL GENETICS MADE EASY, which uses a line-charting method for any number of color mutations within the
same pair. However, these "general" charts have been selectively restated in the style that I have used in one of my other books, Cockatiels
in Color for those wishing to check simple pairings, or to check their work "one mutation at a time."
