Available in PDF, EPUB and Kindle. Book excerpt: As the largest group of extant vertebrates, fish offer an almost limitless number of striking examples of evolutionary adaptation to environmental and biotic selection pressure. The most diverse of all vertebrate groups, the higher taxa of fish traditionally have been classified by morphology and paleontology, with a much smaller input of cytogenetic information. DNA sequence data are exerting an increasingly strong influence on modern fish systematics, challenging the classification of numerous higher taxa ranging from genera to orders. The most fruitful approach, however, involves synthetic analyses of morphology, molecular phylogenetics, comparative karyology, and genome size. Karyotypes of more than 3400 species/subspecies are arranged here by fish systematics and include a list of genome size, sex chromosomes, B chromosomes, polyploidy, and locality of material fish, among others. This volume enables both beginners and advanced researchers to survey the existing literature and facilitates the implementation of an integrative approach to fish systematics. The first book on fish chromosomes in nearly 15 years, it is also the most comprehensive.

This book was released on 2009-03-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not so long ago, karyology was considered a vanguard biological discipline, which could solve nearly all problems of systematics and phylogenetics. We liked to believe in the bright future, in a magician who will appear like a Jack-in-the-box and reveal the truth to us. However, excessive hopes related to the chromosomal study came true only in part. In the meantime, new candidates claimed the place of the magician, i. e. phenetics succeeded by cladistics and now by molecular methods in systematics and phylogeny. Nevertheless, it becomes progressively more ob- ous nowadays that cladistics is just a bright envelope for the fairly primitive and theoretically vulnerable approach that deprives living organisms and their groups of the traces of integrity and reduces them to the plain sum of characters. Modern molecular techniques look more perceptive and may yield more reliable results, although the details are sometimes embarrassing, and comparison with the fossil record does not necessarily reveal their superiority over cladistics. These methods are accessible by research teams with massive funding and good equipment and this strongly decreases the range and diversity of the material studied. However, classi?cations are often created by individual systematists with the restricted access to molecular methods. In this context, karyological techniques are in the preferable position, although they certainly do not provide direct and immaculate markers of taxonomic and p- logenetic relationships: chromosomal study is a morphological method with all its advantages and drawbacks.

Download or read book ABNORMAL KARYOTYPES written by Sana Nimer Abu Shihab and published by Author House. This book was released on 2013-10 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: In my first book (Your Easy Way To Chromosomes), the main topic was about the human chromosomes, their structures, abnormalities, syndromes, and chromosome analysis. In this book I focused on abnormal karyotypes and how chromosomal abnormalities happen. A karyotype is a picture of a person's chromosomes from body cells (blood, hair, or any other tissue), photographing them through a microscope and arranging them in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotype test (alternative names are Chromosome Analysis, Chromosomal Analysis) plays a role in: diagnosis genetic diseases which are related to chromosomal abnormalities, diagnosis some birth defects, and provides clinical utility in the diagnosis and treatment of hematologic malignancies. On the other hand some genetic abnormalities cannot be detected by karyotype analysis such as microdeletions. Karyotype helps clinical cytogeneticist to identify abnormalities by: Counting the number of chromosomes and looking for extra chromosome such as in trisomy 21 or missing chromosome in a karyotype such as in Turner syndrome. Looking for changes in chromosome structure such as chromosomal deletions, duplications, translocations, insertions, inversions and other chromosomal abnormalities.

Book excerpt: Chromosome Identification—Technique and Applications in Biology and Medicine contains the proceedings of the Twenty-Third Nobel Symposium held at the Royal Swedish Academy of Sciences in Stockholm, Sweden, on September 25-27,1972. The papers review advances in chromosome banding techniques and their applications in biology and medicine. Techniques for the study of pattern constancy and for rapid karyotype analysis are discussed, along with cytological procedures; karyotypes in different organisms; somatic cell hybridization; and chemical composition of chromosomes. This book is comprised of 51 chapters divided into nine sections and begins with a survey of the cytological procedures, including fluorescence banding techniques, constitutive heterochromatin (C-band) technique, and Giemsa banding technique. The following chapters explore computerized statistical analysis of banding pattern; the use of distribution functions to describe integrated profiles of human chromosomes; the uniqueness of the human karyotype; and the application of somatic cell hybridization to the study of gene linkage and complementation. The mechanisms for certain chromosome aberration are also analyzed, together with fluorescent banding agents and differential staining of human chromosomes after oxidation treatment.

Download or read book The AGT Cytogenetics Laboratory Manual written by Marilyn S. Arsham and published by John Wiley & Sons. This book was released on 2017-04-24 with total page 1216 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
