This book introduces readers to classical population genetics and the ways in which it can be applied to practical problems, including testing for natural selection, genetic drift, genetic differentiation, population structuring, gene flow and linkage disequilibrium. It provides a comprehensive monograph on the topic, addressing the theory, applications and evolutionary deductions, which are clearly explained using experimental results. It also offers separate chapters on origin, establishment and spread of chromosomal aberrations in populations along with details of culturing, maintaining and using Drosophila ananassae (genetically unique and the most commonly used species along with D. melanogaster) for genetic research. Encompassing topics like genetics, evolution, Drosophila genetics, population genetics, population structuring, natural selection and genetic drift in considerable detail, it provides a valuable resource to undergraduate and postgraduate students, as well as researchers at all level. This book explores some fundamental questions concerning the role of natural selection and genetic drift on the degree of inversion polymorphism. India, with its wide diversity in geo-climatic conditions, provides an excellent platform to conduct such studies. The book showcases sampling records of inversion frequencies in natural Indian populations of D. ananassae that cover more than two decades. It highlights case studies in which sampling data on inversion frequencies was combined with that from earlier surveys, generating a time series that allows the evolutionary dynamics of inversion polymorphism to be explored. Such long time series are rare but nonetheless crucial for studying the evolutionary dynamics of inversion polymorphism. The population-genetic analysis discussed is unprecedented in terms of its temporal (two decades) and spatial (most regions of India covered) scale and investigates the patterns of polymorphic system in D. ananassae to see if there is any temporal divergence. It endeavors to present a holistic picture of inversion polymorphism across the country (India). Chromosomal aberrations, particularly paracentric inversions, are used as a tool for discussing population genetic studies, helping human geneticists, gynecologists and other medical professionals understand why some aberrations are fatal in humans, with affected embryos often not surviving the first trimester of pregnancy, while similar aberrations in Drosophila flies aid in their adaptation to the environmental heterogeneity across the globe.

Selective Sweep deals with the theory and practice of detection of recent adaptive evolution at the genomic level from the patterns of DNA polymorphism. Recent advances in genomic sequencing provide the background for analysis of polymorphic sites in large chromosomal regions or even in whole genome, thus providing the tool for effective identification of loci that are under strong pressure of positive selection. For this reason, the studies of selective sweep, which formerly were of interest mostly to evolutionists, have become widely recognized and appreciated by the large biological community involved in identification of the targets of selection during speciation, host/pathogen interactions, and resistance to chemical agents.

For more than ten years, the distinguished geneticists James F. Crow and William F. Dove have edited the popular "Perspectives" column in Genetics, the journal of the Genetics Society of America. This book, Perspectives on Genetics, collects more than 100 of these essays, which cumulatively are a history of modern genetics research and its continuing evolution.

All organisms--from the AIDS virus, to bacteria, to fish, to humans--must evolve to survive. Despite the central place of evolution within biology, there are many things that are still poorly understood. For Charles Darwin, the driving force behind all evolution was natural selection. More recently, evolutionary biologists have considered that many mutations are essentially neutral with respect to natural selection. Many questions remain. Are molecular differences between species adaptive? Are differences within species adaptive? Modern biotechnology has enabled us to identify precisely the actual DNA structure from many individuals within a population, and thus to see how these DNA sequences have changed over time and to answer some of these questions. At the same time, this knowledge poses new challenges to our ability to understand the observed patterns. This exciting volume outlines the biological problems, provides new perspectives on theoretical treatments of the consequences of natural selection, examines the consequences of molecular data, and relates molecular events to speciation. Every evolutionary biologist will find it of interest.

This book focuses on drosophila as an especially useful model organism for exploring questions of evolutionary biology in the full range of evolutionary studies: population genetics, ecology, ecological genetics, speciation, phylogenetics, genome evolution, molecular evolution, and development. The author presents an integrated view of evolutionary biology as elucidated in this single organism. Special effort is made to point out holes in our knowledge and areas particularly ripe for new investigation.

Genetic studies aimed at understanding the origin of species are dominating major scientific journals. In the past decade, genetic tools that were previously available only in model systems have become accessible to investigators working on nearly all species. Concurrent with these technical advances has been an increase in understanding of both the importance of considering the ecological context of speciation and testing hypotheses about causes for species formation. Many recent studies suggest a prominent role of sexual selection in species formation. These advances have produced a need for a synthesis of what we now understand about speciation, and perhaps more importantly, where we should go from here. In this volume, several leading investigators and rising stars have contributed reviews and/or novel primary research findings aimed at understanding the ultimate mystery on which Darwin named his most famous and influential book. Fundamental to the origin of species is the evolution of mate choice systems. This collection of papers discusses burgeoning genetic, evolutionary, and ecological approaches to understanding the origins of mating discrimination and causes of premating reproductive isolation both within and between species. The individual contributions span a wide spectrum of disciplines, taxa, and ideas (some controversial). This synthesis brings together several of the most recent ideas with supporting empirical data. This book will be of particular interest to both undergraduate and postgraduate researchers and students and researchers in the field of evolutionary biology, genetics and animal behaviour.
