Completely updated and revised, the third edition of this essential textbook describes the basic genetics of the horse including coat colour, parentage, medical and population genetics, cytogenetics, performance, breeding systems and genetic conservation, as well as the many recent advances in genomics.

Equine Color Genetics, Fourth Edition presents a detailed examination of the color variation in horses and donkeys and the genetic mechanisms that produce color variations. Thoroughly covers the basic colors in horses, including bay, chestnut, black, and brown Details the genetic basis of the colors built from the basic coat color, including dilutions and white patterning Provides an explanation of genetic mechanisms that determine coat color Presents a thorough revision and update, including new advances in molecular genetics, biochemistry, molecular mechanisms, genetic loci, coat colors before domestication, and more Offers a new introduction describing the principles of genetics and genomics research to help outline how knowledge is discovered and to assist the reader in understanding concepts covered in the book

Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Behavior is shaped by both genetics and experience--nature and nurture. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. - Includes four new chapters on dog and fox behavior, pig behavior, the effects of domestication and horse behavior - Synthesizes research from behavioral genetics, animal science, and veterinary literature - Broaches fields of behavior genetics and behavioral research - Includes practical applications of principles discovered by behavioral genetics researchers - Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats

There are still many unknowns in the breeding of Thoroughbreds, but the international research coalition known as the Equine Genome Project is facilitating many new exciting discoveries. Dr. Matthew Binns is a leader of the project, an enterprise set up to map the equine genome, and with racing historian and bloodstock authority Tony Morris has written this important book on the theory, practice, art and science of Thoroughbred breeding. This long-awaited book describes how man came to express pedigree and to develop theories about it, and how practical breeders behaved in the light of their understanding. IT explains why many theories--including some still widely granted credibility today--are fallacious, examines the very real progress in knowledge since the principles of genetics were discovered, and focuses on the exciting developments of the last few years, when eminent geneticists have applied their expertise to the subject of the Thoroughbred. It has been the authors' endeavor to present the information in a form that may be readily understood by anyone who shares a love of the Thoroughbred and a fascination with what makes him what he is. Packed with absorbing history and cutting-edge science, this is a fascinating and illuminating book.
