Although the field of quantitative genetics - the study of the genetic basis of variation in quantitative characteristics such as body size, or reproductive success - is almost 100 years old, its application to the study of evolutionary processes in wild populations has expanded greatly over the last few decades. During this time, the use of 'wild quantitative genetics' has provided insights into a range of important questions in evolutionary ecology, ranging from studies conducting research in well-established fields such as life-history theory, behavioural ecology and sexual selection, to others addressing relatively new issues such as populations' responses to climate change or the process of senescence in natural environments. Across these fields, there is increasing appreciation of the need to quantify the genetic - rather than just the phenotypic - basis and diversity of key traits, the genetic basis of the associations between traits, and the interaction between these genetic effects and the environment. This research activity has been fuelled by methodological advances in both molecular genetics and statistics, as well as by exciting results emerging from laboratory studies of evolutionary quantitative genetics, and the increasing availability of suitable long-term datasets collected in natural populations, especially in animals. Quantitative Genetics in the Wild is the first book to synthesize the current level of knowledge in this exciting and rapidly-expanding area. This comprehensive volume also offers exciting perspectives for future studies in emerging areas, including the application of quantitative genetics to plants or arthropods, unraveling the molecular basis of variation in quantitative traits, or estimating non-additive genetic variance. Since this book deals with many fundamental questions in evolutionary ecology, it should be of interest to graduate, post-graduate students, and academics from a wide array of fields such as animal behaviour, ecology, evolution, and genetics.

Statistical methods for the analysis of quantitative trait locus (QTL), in conjunction with genome-wide screening technologies, are today yielding exciting results in the study of human disease, experimental organisms, and agriculture. In Quantitative Trait Loci: Methods and Protocols, Drs. Nicola Camp and Angela Cox have assembled a highly experienced panel of statistical geneticists who demonstrate in a step-by-step fashion how to use this powerful methodology and associated software for the detection and fine mapping of quantitative trait loci. Writing for the nonmathematician, these experts guide the investigator from the design stage of a project onwards, providing detailed explanations of how best to proceed with each specific analysis, to find and use appropriate software, and to interpret results. Worked examples, citations to key papers, and useful variations and/or extensions to standard methods are included that ease the reader toward understanding and successful studies. Among the cutting-edge techniques presented are QTDT methods, variance components methods, and the Markov chain Monte Carlo method for joint linkage and segregation analysis. Up-to-date and highly practical, Quantitative Trait Loci: Methods and Protocols makes available to nonmathematical investigators a step-by-step guide to the productive use today of all the latest techniques for localizing genes involved in complex quantitative traits.

This book, suitable for numerate biologists and for applied statisticians, provides the foundations of likelihood, Bayesian and MCMC methods in the context of genetic analysis of quantitative traits. Although a number of excellent texts in these areas have become available in recent years, the basic ideas and tools are typically described in a technically demanding style and contain much more detail than necessary. Here, an effort has been made to relate biological to statistical parameters throughout, and the book includes extensive examples that illustrate the developing argument.

The impetus for this book arose out of my previous book, The Evolution of Life Histories (Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory. However, as the book was concerned with the evolution of life histories and traits connected to this, the presence of quantitative genetic variation was an underlying theme throughout. Much of the focus was placed on optimality theory, for it is this approach that has proven to be extremely successful in the analysis of life history variation. But quantitative genetics cannot be ig nored, because there are some questions for which optimality approaches are inappropriate; for example, although optimality modeling can address the ques tion of the maintenance of phenotypic variation, it cannot say anything about genetic variation, on which further evolution clearly depends. The present book is, thus, a natural extension of the first. I have approached the problem not from the point of view of an animal or plant breeder but from that of one interested in understanding the evolution of quantitative traits in wild populations. The subject is large with a considerable body of theory: I generally present the assumptions underlying the analysis and the results, giving the relevant references for those interested in the intervening mathematics. My interest is in what quantitative genetics tells me about evolutionary processes; therefore, I have concentrated on areas of research most relevant to field studies.

The focus of this work was the study of the genetic determination of kernel morphology and end-use quality in wheat (Triticum aestivum L.). Chapter 1 was a QTL analysis of milling and baking quality in a soft x hard wheat cross. Small- and large-sample milling data were analyzed with control for the effect of the Hardness gene on chromosome 5D. QTL were detected on 1A, 1B, 1A/D, 2A, 2B, 2D, 3A/B, 4B, 5B and 6B. The hard wheat parent contributed favorable alleles for soft wheat, and vice versa, indicating that hard x soft crosses have potential for quality improvement of either class. Chapter 2 reports a QTL analysis of kernel morphology in two mapping populations. An improved method of evaluation of kernel shape through digital image analysis revealed significant QTL on homoeologous groups 2, 4, 5 and 6 in both populations. The most important QTL were detected on chromosome 2D, in the population RxG, for kernel lateral dimensions, and on 5B, in the population SxO, for kernel length. In Chapter 3, a genetic model for the association between markers and genes was proposed for predicting marker-assisted selection response and potential of populations for association mapping. The application of mixed-effects models for association analysis was elaborated and the potentials and limitations of different populations for association mapping, integrated with plant breeding practice, were compared. Association mapping of kernel morphology and milling quality, on chromosomes 2D, 5A and 5B, was conducted on a panel of 95 soft winter wheat cultivars, and those results are reported in Chapter 4. The extent of LD was estimated to be less than 1 cM on chromosome 2D and approximately 5 cM in the centromeric region of 5A. Population structure was estimated with 36 unlinked markers and included in a mixed-effects model for association analysis. Correction for multiple testing was done through permutation within chromosomes. The results agreed well with the QTL analysis of Chapter 2, and alleles potentially useful for selection were identified. This study demonstrated that association mapping could enhance the usefulness of previous QTL results for marker-assisted selection.
