Abstract
This third edition provides basic information on genetics in an easy-to-understand format. As before, the book includes introductory chapters on basic genetics that review terminology and fundamental concepts. At the same time, the text contains very specific information about the DNA variants associated with traits, scientific speculation about how those traits came to be, and advice on how to apply the wide variation occurring among horses. It is not a book to read through at one sitting. The reader may want to simply peruse the table of contents and select sections pertaining to their interests. References are included to the original work if the reader wants details; however, these detailed studies are not necessary for a useful understanding of this new information. The book covers a wide range of topics but not everything. This is an introductory text and the author hopes that the lessons learned from the material in the book will make it possible to follow and understand the many exciting discoveries that did not fit or that are currently emerging areas of interest.
