Available in PDF, EPUB and Kindle. Book excerpt: When Richard Goldschmidt' coined the term "intersexuality" in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters. However, as knowledge of the bewildering variability present in the sexual orga nization of members of the animal kingdom has increased, the original meaning of the word has changed. Today many authors define inter sexuality as "the presence of both male and female characteristics, or of intermediate sexual characteristics, in a single individual".2 This more extensive and widely accepted concept justifies the title of our book •. Among all the anatomical and physiological features of living organisms the reproductive system has a unique importance for the perpetuation of the species. Conversely, reproductive processes are of little or no account for the viability of the individual. Therefore, within the framework of general biology reproduction has all too often been looked at solely from the point of view of genetics. Lively discussions about genotypic versus phenotypic sex determination long dominated the sci entific literature on sexuality in animals; this one-sided emphasis has tended to obscure many important facets of an organism's ability to reproduce. Recent developments in current biological research have brought the classic problem of sex differentiation into focus again, and the rapid progress being made in comparative endocrinology has added a new di mension to the study of reproductive biology.

Download or read book Sex Determination, Differentiation and Intersexuality in Placental Mammals written by R. H. F. Hunter and published by Cambridge University Press. This book was released on 1995-03-09 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do males become male and females become female? And what are the consequences if the decision is not incisive? Drawing upon interests in animal genetics and molecular biology, the author endeavours to answer these difficult yet fascinating questions. Originally published in 1995, this book describes the genetic determination of sex and examines how sexual organs are differentiated. Using examples of intersexuality, chimaeras and asymmetries, the book describes the underlying molecular basis of sex determination and sexual differentiation, and focuses on the critical role of the rate of embryonic development in these vital processes. Male precocity is a recurrent theme, as is the involvement of Sertoli cells and their secretion of anti-Müllerian hormone. An invaluable book for reproductive physiologists, geneticists and developmental biologists whose interests may extend from animal science through veterinary medicine to human clinical medicine.

Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is neuroendocrinology, that branch of biological science devoted to the interactions between the two major integrative organ systems of animals-the endocrine and nervous systems. Although this science today reflects a fusion of endocrinology and neurobiology, this synthetic ap proach is relatively recent. At the beginning of the 20th century, when the British physiologists, Bayliss and Starling, first proposed endocrinology to be an independent field of inquiry, they went to great lengths to establish the autonomy of chemical secretions in general and their independence from nervous control in particular (Bayliss, W. M. , and Starling, E. H. , 1902, The mechanism of pancreatic secretion,]. Physiol. 28:325). They argued with Pav lov, who said that there was a strong influence of the nervous system on the gastrointestinal phenomena the endocrinologists were studying. For several decades, the English physiologists prevailed, at least in the West; and Pavlov's critique was not taken to heart by the practitioners of the newly emerging discipline of endocrinology. Through the work of Harris, the Scharrers, Sawyer, Everett, and others, there has been something of a scientific detente in the latter half of this century; the hybrid field of neuroendocrinology is now regarded as one of the corner stones of modern neural science and is of fundamental importance in basic and clinical endocrinology.

This book was released on 2011-04-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this fascinating book is how and why males become male and females become female and what factors may lead to intersexuality. Coming from a molecular biology perspective, Professor Hunter uses examples of intersexuality, chimeras, and asymmetries to describe the underlying molecular basis of sexual differentiation and determination. He explains how genetic instruction can prompt myriad developmental problems. Reproductive physiologists and geneticists from agriculture to veterinary medicine will find this a stimulating topic.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Morphogenesis, Volume 6 considers the significant advances in various aspects of morphogenesis. This volume is composed of seven chapters that specifically cover the biological, morphological, and embryological aspects of cell growth and development. The opening chapter deals with the classification, progression, genetic aspects, and experimental induction of teratomas. The next chapter focuses on insect morphogenesis, its formation of surface patterns, the gradient organization of the epidermis, and the three-dimensional patterns resulting from cycles of activity in time. A chapter discusses the factors that control the initiation of hemoglobin synthesis, with a particular emphasis on studies of the chick and amphibian embryo. These topics are followed by surveys on heteroblastic development in vascular plants, the ultrastructure of the nucleus, and the experimental alterations of the developmental cytogenetic mechanisms. The final chapter examines the epigenetic aspect of developments in sexual organogenesis. This book is directed primarily toward developmental biologists.

Download or read book Sex Chromosomes and Sex Determination in Vertebrates written by Alberto J. Solari and published by CRC Press. This book was released on 1993-10-22 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cloning of the SRY gene and the attainment of XX mice transgenic for the Sry gene opened a new era in research on sex determination. This book surveys current knowledge of sex chromosomes and sex determination in all vertebrate classes, relying on the restriction of genetic recombination in sex chromosomes as the unifying concept of this subject. The book's interdisciplinary approach integrates contributions from the fields of cytogenetics, molecular biology, developmental biology, and evolutionary genetics. A detailed treatment of the meiotic behavior of sex chromosomes is featured, and the entire text is supplemented by numerous schemes, drawings, and electron micrographs. The book will be valuable to general cytogeneticists, vertebrate zoologists, and veterinarian and medical practitioners interested in the foundations of sex determination and the current knowledge of sex chromosomes. It will also interest students in advanced undergraduate and graduate courses in these areas.

Available in PDF, EPUB and Kindle. Book excerpt: Following an opening chapter by the late Susumu Ohno on paralogues of sex-determining genes, the five best-studied genes essential for early mammalian gonadal development are portrayed in detail: SF-1 and WT1 and their roles in early events in gonadal development, SRY and SOX9 in testis determination, and the anti-testis gene DAX-1. Subsequent chapters look at the roles of these genes in sex determination in marsupial mammals, birds, reptiles, amphibians and fish, and review the different sex-determining mechanisms, genetic and environmental, that operate in these different vertebrate classes. Two insights emerge: one, that the same basic set of genes appears to operate during early gonadal development in all vertebrates, despite the differences in mechanisms; the other, that sex determination in vertebrates results from a complex network of regulatory interactions and not from a simple hierarchical cascade of gene actions.

This book was released on 2012-12-06 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.

Available in PDF, EPUB and Kindle. Book excerpt: Oral birth in the Australian gastric brooding frog Rheobatrachus sUus 2 Preface I have deliberately chosen the title picture to the preface, which shows the oral birth of a young gastric brooding frog (Rheobatrachus situs), to draw the reader's attention to the preface since I wish to explain why the book was written and illustrated in the way it now appears. The book has grown out of the material of a lecture course taking 3 to 4 hours per week each semester that I have given for several years at the Ruhr-University Bochum as the theoretical basis for an intensive 4 week practical course on vertebrate reproduction for students of biology. For various reasons I am a hardened opponent of giving lecture notes to the students. On the other hand I found that my students made great efforts to work through and supplement their own lecture notes by studying the literature. However, there are no suitable textbooks on vertebrate reproduction written in German and the standard work in this field is now several decades old and deals mainly with mammals. The students were therefore often frustrated in their efforts given the limited time they had available. I have therefore decided to present here the most important structural and functional aspects of vertebrate reproduction and include other material to extend the framework of my original lectures.
