The g factor is about individual differences in mental abilities. In factor analyses of any and every large and diverse collection of measures of mental abilities, however varied the content of knowledge and skills they call upon, g emerges as the largest, most general source of differences between individuals and between certain subpopulations.Jensen fully and clearly explains the psychometric, statistical, genetic, and physiological basis of g, as well as the major theoretical challenges to the concept. For decades a key construct in differential psychology, the g factor's significance for scholars and researchers in the brain sciences as well as education, sociology, anthropology, evolutionary psychology, economics, and public policy is clearly evident in this, the most comprehensive treatment of g ever published.

    Based on twenty years of research at the Jackson Laboratory, this is the single most important and comprehensive reference work on the behavior of dogs ever complied."Genetics and the Social Behavior of the Dog is one of the most important texts on canine behavior published to date. Anyone interested in breeding, training, or canine behavior must own this book."—Wayne Hunthausen, D.V.M., Director of Animal Behavior Consultations"This pioneering research on dog behavioral genetics is a timeless classic for all serious students of ethology and canine behavior."—Dr. Michael Fox, Senior Advisor to the President, The Humane Society of the United States"A major authoritative work. . . . Immensely rewarding reading for anyone concerned with dog-breeding."—Times Literary Supplement"The last comprehensive study [of dog behavior] was concluded more than thirty years ago, when John Paul Scott and John L. Fuller published their seminal work Genetics and the Social Behavior of the Dog."—Mark Derr, The Atlantic Monthly"Genetics and the Social Behavior of the Dog is essential reading for anyone involved in the breeding of dogs. No breeder can afford to ignore the principles of proper socialization first discovered and articulated in this landmark study."-The Monks of New Skete, authors of How to Be Your Dog's Best Friend and the video series Raising Your Dog with the Monks of New Skete.

    What wasoriginally envisioned as a single text has now become two, with the focus of this first book being on the basic biology and methods of analysis of quantitative characters.Three major features of Genetics and Analysis of Quantitative Traits distinguish it from earlier work. First, it reflects the explosive influx over the past few years of quantitative-genetic thinking into evolutionary biology. Second, in animal breeding, enormous strides have been made in thedevelopment of new techniques for estimating breeding values (for the purposes of identifying elite individuals in selection programs) and for estimating variance components from samples of complex pedigrees. In this text's last two chapters, the authors outline the basic principles of complexpedigree analysis, without getting bogged down in technical details. Third, Genetics and Analysis of Quantitative Traits provides a broad overview of the newly emerging array of techniques for quantitative-trait loci (QTL) analysis, currently one of the most active fields of quantitative-geneticresearch.Genetics and Analysis of Quantitative Traits contains numerous fully-worked examples and illustrations of theoretical concepts, as well as over 2,000 references with indices by subject, author, and organism. In addition, the authors maintain a World Wide Web site featuring up-to-date lists ofcomputer programs and on-line resources, and added information on various topics presented in the text.
