Book Description
Introduction When the study of heredity and variation first came to be treated as a scientific subject-and this, one must remember, was only just over a hundred years ago-there was an unfortunate separation between the disciplines of cytology and experimental breeding. This separation was based partly on a lack of understanding and partly on a lack of the desire to understand. Even WILLIAM BATESON, the first apostle of mendelism in England, had a blind spot for cytology and for many years dogmatically refused to believe that MENDEL'S determinants were transmitted and distributed by the chromosomes. This separation between cytology and experimental breeding is one which persists, in a measure, even today, simply because there are two quite different, though complementary, techniques available for the study of heredity and variation. On the one hand, one can study directly the structure and behaviour of the actual vehicles which transmit the genetic determinants from one generation to the next. This is the method employed by those who study genetics through a microscope. The alternative method is that used by the experimental breeder who, in default of being able to watch the hereditary factors segregate from each other directly, is obliged to examine the constitution of the germ cells indirectly by sampling, and usually at random, the products of a controlled mating.

A Dictionary of Genetics
Author: Robert C. KingPublisher: Oxford University Press, USA
ISBN: 0195094417
Category : Genetics
Languages : en
Pages : 452
Book Description
Modern genetics began in 1900 with the rediscovery of Mendel's paper, and now the sequencing of the human genome has brought the first century of progress in this field to a triumphant conclusion. Genetics has entered a new era with the advent of genomic and proteomic approaches, and the knowledge in no other biological discipline is advancing as rapidly as that in molecular genetics and cell biology. Proliferation of new terms inevitably accompanies such exponential growth. The sixth edition of A Dictionary of Genetics addresses the need of students and professionals to have access to an up-to-date reference source that defines not only the most recently coined terms, but in many cases also presents important ancillary encyclopedic information.A Dictionary of Genetics has a broader coverage than its name implies, since it includes definitions of strictly genetic words along with a variety of non-genetic terms often encountered in the literature of genetics. There are about 7,000 definitions, and tables or drawings that illustrate 395 of these. In addition to the main body of the dictionary, this work features new Appendices covering the genomic sizes and gene numbers of about 30 organisms ranging from the smallest known virus to humans, an up-to-date listing of internet addresses for easy access to genetic databanks, and a list of developments, inventions and advances in genetics, cytology, and evolutionary science from the past 400 years. These 900 entries, covering a period from 1590 to 2001, are also cross-referenced in the definitions that occur in the body of the dictionary. No other genetics dictionary supplies definitions cross-referenced to chronology entries or has species entries cross-referenced to an appendix showing the position of each organism in a taxonomic hierarchy. These features make A Dictionary of Genetics the most important lexicon in this field.

Quantitative genetic variation
Author: James N. Jr. ThompsonPublisher: Elsevier
ISBN: 0323156029
Category : Science
Languages : en
Pages : 327
Book Description
Quantitative Genetic Variation describes some of the experimental approaches to quantitative genetic variation, along with their potential applications and limitations. It considers one of the most widely applicable tools, i.e., biometrical analysis, as well as individual polygenic effects, specific components of a quantitative genetic trait, and artificial selection, and it shows how selection experiments can address specific developmental and genetic questions. Organized into four sections encompassing 17 chapters, this volume begins with a historical overview of the study of quantitative genetic variation, along with genetic variation in fungi and Drosophila. It then discusses the biometrical approach to quantitative variation, selection theory and analysis, uses and limitations of polygene mapping, and computer simulation of the breeding program for polygene location. The reader is also introduced to genes affecting quantitative aspects of physiology in rodents, as well as cytological markers and quantitative variation in wheat. This book will be extremely useful to students, researchers, and geneticists.

Research on Chrysomelidae, Volume 1
Author: Pierre JolivetPublisher: BRILL
ISBN: 9047427858
Category : Science
Languages : en
Pages : 430
Book Description
There are an estimated 40,000 species of chrysomelids, or leaf beetles, worldwide. These biologically interesting and often colorful organisms, such as the tortoise beetles, have a broad range of life histories and fascinating adaptations. For example, there are chrysomelids with shortened wings (brachypterous) and elytra (brachelytrous), other species are viviparous, and yet other leaf beetles have complicated anti predator-parasitoid defenses. Some species, such as corn rootworms (several species in the genus Diabrotica) constitute major agricultural crop pests. Research on Chrysomelidae 1 is a the first of an intended series of volumes on the Chrysomelidae edited by Jolivet, Santiago-Blay, and Schmitt.
