Here, in one volume, is a wide and varied assessment of the major breeding systems and theories, as well as the history and background of each. The writers give readers all the necessary information they need to implement the theory and make it part of a breeding program. They also verify the relative scientific validity of the theories and various approaches to breeding. This, more than any other factor, sets this book apart from other attempts to offer breeding theory to owners and breeders. The authors ask, "Does this really work and, if so, how often has it been proven or disproven?"
By studing the varied breeding approaches and theories, modern breeders can use the information that best fits their breeding program.
