"It is close to being a masterpiece...could well be the classicpresentation of the area." Warren J. Ewens, University ofPennsylvania, USA Population genetics is concerned with the study of the genetic,ecological, and evolutionary factors that influence and change thegenetic composition of populations. The emphasis here is on modelsthat have a direct bearing on evolutionary quantitative genetics.Applications concerning the maintenance of genetic variation inquantitative traits and their dynamics under selection are treatedin detail. * Provides a unified, self-contained and in-depth study of thetheory of multilocus systems * Introduces the basic population-genetic models * Explores the dynamical and equilibrium properties of thedistribution of quantitative traits under selection * Summarizes important results from more demanding sections in acomprehensible way * Employs a clear and logical presentation style Following an introduction to elementary population genetics anddiscussion of the general theory of selection at two or more loci,the author considers a number of mutation-selection models, andderives the dynamical equations for polygenic traits under generalselective regimes. The final chapters are concerned with themaintenance of quantitative-genetic variation, the response todirectional selection, the evolutionary role of deleteriousmutations, and other topics. Graduate students and researchers in population genetics,evolutionary theory, and biomathematics will benefit from thein-depth coverage. This text will make an excellent referencevolume for the fields of quantitative genetics, population andtheoretical biology.
