Book Description
Cytogenetics of Aneuploids deals with the cytogenetic aspects of aneuploidy in plants, emphasizing the trisomics, monosomics, and nullisomics and cytogenetics of substitution lines as well as alien additions and substitutions. An account of aneuploidy in animals and man is also given. This volume is organized into 12 chapters and begins with an overview of terminology and chromosomal formulas, along with a brief history of the cytogenetics of aneuploids as a field of enquiry. The next chapters review the entire literature on trisomics, their sources, cytology, transmission rates, genetics, morphology, anatomy, physiology, and biochemistry. The discussion then shifts to monosomics and nullisomics, including their sources and cytology as well as breeding behavior, morphology, and genetic studies. Other uses of monosomics and nullisomics are considered. The following chapters deal with intervarietal substitutions and alien additions and substitutions, emphasizing different methods of producing substitution lines and their utility in genetic analysis and practical plant breeding programs. The book concludes by describing special features of aneuploidy in animals and highlighting specific cases of aneuploidy in the animal kingdom. This book will be of interest to plant breeders and geneticists.

Book Description
The "Symposium on Aneuploidy: Etiology and Mechanisms" was held at the Carnegie Institution of Washington Auditorium from March 25-29. 1985. This Symposium developed as a consequence of the concern of the Environmen tal Protection Agency with the support of the National Institute of Envi ronmental Health Sciences about human exposure to environmental agents that cause aneuploidy. The program was chosen to explore what is currently known about the underlying causes, the origins, and the extent of the prob lem of human aneuploidy, and whether exposure to environmental agents is assodated with an increased incidence of aneuploidy in humans. Basic research findings in the area of mitosis and meiosis were presented and related to possible mechanisms of how aneuploidy may be produced spontane ously and chemically. A survey of data regarding the chemical induction of aneuploidy in experimental organisms was presented. Outstanding scientists from different fields were invited to cover a broad perspective of aneu ploidy from the molecular aspects to the human situation. We hope that the publication of the proceedings will share the enthu siasm of the meeting and its scientific content. The topic of aneuploidy has received little attention and it is the purpose of this Volume to establish a scientific basis for assessing health risks posed by environ mental exposures to aneuploidy-inducing chemicals.

Book Description
An introductory discussion of basic chromosome structure and function preceeds the main text on the application of cytogenetic approaches to the analysis of the manipulation of both the genetic make-up and the genetic transmission system of plant breeding material. Analysis using light and electron microscopy, segregations and molecular techniques, yields information for assessing the material before and after manipulation. Much attention is given to quantitative methods. Manipulation not only involves the construction of specific genotypes, but also chromosomal transmission systems. Although analysis and manipulation in the somatic cycle are considered, the focus is on the generative cycle, with emphasis on analysis and subsequent segregation of specifically constructed material. The book is intended for plant breeders and other scientists interested in the analysis and manipulation of breeding material at the chromosomal level. Comparisons with molecular and cell biological approaches are made, and the potential of the various methods is evaluated.

Book Description
Aneuploidy is the most commonly occurring type of chromosome abnormality. It occurs usually because of segregation errors that take place during female meiosis. Most aneuploid pregnancies do not survive in utero and in the great majority of cases demise happens during the first few weeks of uterine life. This publication investigates the causes of aneuploidy in humans and its effects at different life stages. This issue is accordingly divided into three main sections: the first, 'Aneuploidy at Different Life Stages', provides an overview of abnormalities in sperm and oocytes. In addition, current literature dealing with inherited aneuploidy arising from germinal mosaicism is reviewed. The second section provides in-depth coverage of aneuploidy during embryogenesis together with articles about somatic changes. Furthermore, an exciting collection of up-to-date articles by highly regarded experts in the field explore the topic of genetic regulation of chromosome segregation. The final section is devoted to 'Environment and Epigenetics', two critical factors in the genesis of aneuploidy. Providing a valuable overview this issue will be of interest not only to those engaged in genetic research but also to clinicians concerned with fetal medicine and with infertility. Furthermore, embryologists who need to be familiar with the latest findings relating to embryonic aneuploidy will doubtless appreciate these reviews.
