In the summer of 1989, one of us (SLG), along with his mentor, Dorothy Warb- ton, attended the Tenth International Workshop on Human Gene Mapping. The me- ing was held at Yale University in celebration of the first such event, which also took place there. This meeting was not open to the general public; one had to have contributed to mapping a gene to be permitted to attend. The posters, of course, were therefore all related to gene mapping, and many were covered with pretty, colorful pictures of a novel, fluorescent application of an old technology, in situ hybridization. Walking through the room, Dorothy remarked that, because of this new FISH technique, ch- mosomes, which had become yesterday’s news, were once again “back in style. ” Approximately three years later, a commercial genetics company launched a FISH assay for prenatal ploidy detection. A substantial number of cytogeneticists across the country reacted with a combination of outrage and panic. Many were concerned that physicians would be quick to adopt this newfangled upstart test and put us all on the unemployment line. They did not at the time realize what Dorothy instinctively already knew—that FISH would not spell the doom of the cytogenetics laboratory, but it would, rather, take it to new heights.

The book is basically intended to accompany a course in cytogenetics students of Genetics and Plant Breeding . Students are presumed to have knowledge of basics in genetics, cytology and plant breeding but in the present book with the help of diagrams and explanations it has been attempted that even a beginner could grasp the core elements of the subject. The book has been strictly organized on the basis of course curriculum being taught in Universities. All the topics covered in the book have been ordered in a crisp and comprehensible manner avoiding complexities of a traditional textbook since it is a simply a guide book to supplement but not supplant the main texts.

Cytogenetics is the study of chromosome morphology, structure, pathology, function, and behavior. The field has evolved to embrace molecular cytogenetic changes, now termed cytogenomics. Cytogeneticists utilize an assortment of procedures to investigate the full complement of chromosomes and/or a targeted region within a specific chromosome in metaphase or interphase. Tools include routine analysis of G-banded chromosomes, specialized stains that address specific chromosomal structures, and molecular probes, such as fluorescence in situ hybridization (FISH) and chromosome microarray analysis, which employ a variety of methods to highlight a region as small as a single, specific genetic sequence under investigation. The AGT Cytogenetics Laboratory Manual, Fourth Edition offers a comprehensive description of the diagnostic tests offered by the clinical laboratory and explains the science behind them. One of the most valuable assets is its rich compilation of laboratory-tested protocols currently being used in leading laboratories, along with practical advice for nearly every area of interest to cytogeneticists. In addition to covering essential topics that have been the backbone of cytogenetics for over 60 years, such as the basic components of a cell, use of a microscope, human tissue processing for cytogenetic analysis (prenatal, constitutional, and neoplastic), laboratory safety, and the mechanisms behind chromosome rearrangement and aneuploidy, this edition introduces new and expanded chapters by experts in the field. Some of these new topics include a unique collection of chromosome heteromorphisms; clinical examples of genomic imprinting; an example-driven overview of chromosomal microarray; mathematics specifically geared for the cytogeneticist; usage of ISCN’s cytogenetic language to describe chromosome changes; tips for laboratory management; examples of laboratory information systems; a collection of internet and library resources; and a special chapter on animal chromosomes for the research and zoo cytogeneticist. The range of topics is thus broad yet comprehensive, offering the student a resource that teaches the procedures performed in the cytogenetics laboratory environment, and the laboratory professional with a peer-reviewed reference that explores the basis of each of these procedures. This makes it a useful resource for researchers, clinicians, and lab professionals, as well as students in a university or medical school setting.

This comprehensive and well-written text provides thorough understanding of the principles and applications of cytogenetics and genetics in an easy-to-understand style. The text is divided into Four parts. Part I on Principles of Cytogenetics deals with evolution and structure of cell, cell division and change, and structure of genetic material. Part II on Principles of Genetics provides detailed discussions on transmission, distribution and arrangement of genetic material, and evolution of species. Part III which is on Molecular Genetics discusses functions of genetic material including biotechnology and genetic engineering, and the last Part IV on Quantitative Genetics deliberates on the course of genetic material in populations. A historical approach to the subject has also been presented to show the continuity and progress. KEY FEATURES: Incorporates latest and up-to-date information on the subjects covered. Provides review questions at the end of each chapter to test the understanding of the concepts discussed. Gives ample references to explore further. Includes a glossary of important terms. The book is eminently suitable for undergraduate and postgraduate students of botany, agriculture, zoology and biotechnology for courses in genetics/genetics and cytogenetics. In addition, the book would also be useful to students appearing in different competitive examinations.
