Book excerpt: This volume provides an in-depth look at the genetic influences that contribute to the development of alcoholism. Part I: Epidemiologic Studies contains five chapters that examine the various approaches employed in the study of the genetics of alcoholism. It provides a historical perspective and details all the essentials of this subject. Part II: Selective Breeding Studies highlights the results of research involving the selective breeding of rodents. This type of research has produced homogenous strains exhibiting specific behavioral responses considered significant in the development and maintenance of alcohol dependence. The studies presented in Part III: Phenotypic Studies investigate and analyze phenotypic markers that serve as correlates to the genotypic determinants of alcoholism. Through its broad scope, this volume provides for the first time a panoramic view of the knowledge available on the hereditary influences of alcoholism.
