Book Description
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.

Book Description
"1 Jind published lectures insipid. " ALEXANDER VON HUMBOLDT ta LOUIS AGASSIZ, January 15, 1840 Many things speak against the publication of lectures. The effect of the spoken word is very different from that of the written word. Repeated recapitulations, which help the listener under stand, are unnecessary, and the overtones of speech disappear in print. A lecture, particularly when not meant for beginners and not offered in preparation for a test, permits the privilege of subjective choice, and when published it is rightly open to criticism. So it has not been easy for me to determine to publish these lectures, which I have given in various forms in Gattingen and then again in Tiibingen. In the end, the deciding factors were the urging of my students, the encouragement of colleagues, many of whom I was delighted to see among my listeners, and the wish of my publisher, with whom I have enjoyed a friendly relationship for a long time. The final form of the text is basically a copy, and thus reallectures are the heart of it. If the lectures had not been taken down repeatedly, this book would not have appeared; 1 could not have undertaken a textbook-sized compilation of this material. With all the changes, the organization, the line of thought, and of ten the composition of the lectures themselves were retained. They may recall to my listeners of old the hours we spent together.

Book Description
Anyone wishing to tap the research potential of the hundreds of Drosophila species in addition to D.melanogaster will finally have a single comprehensive resource for identifying, rearing and using this diverse group of insects. This is the only group of higher eukaryotes for which the genomes of 12 species have been sequenced.The fruitfly Drosophila melanogaster continues to be one of the greatest sources of information regarding the principles of heredity that apply to all animals, including humans. In reality, however, over a thousand different species of Drosophila exist, each with the potential to make their own unique contributions to the rapidly changing fields of genetics and evolution. This book, by providing basic information on how to identify and breed these other fruitflies, will allow investigators to take advantage, on a large scale, of the valuable qualities of these other Drosophila species and their newly developed genomic resources to address critical scientific questions.* Provides easy to use keys and illustrations to identify different Drosophila species* A guide to the life history differences of hundreds of species* Worldwide distribution maps of hundreds of species* Complete recipes for different Drosophila diets* Offers an analysis on how to account for species differences in designing and conducting experiments* Presents useful ideas of how to collect the many different Drosophila species in the wild

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.

Book Description
Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. Volumes in this series contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume nine focuses on Drosophilidae (Diptera). (Series: World Catalogue of Insects)
