Approximately one third of sSMC carriers show clinical symptoms, while the remaining two thirds manifest no phenotypic effects. This guide represents the first book ever published on this topic. Found inside – Page 79In mitosis there is one cell division which produces two new cells. In meiosis there are two cell divisions, and four new cells are formed. In mitosis, the new cells have the same number of chromosomes as the parent cell, but in meiosis the new ...

Found insideThe first three editions of this acclaimed book presented a much-needed conceptual synthesis of this rapidly moving field. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of ... In addition, changing perspectives on meiosis and sex have led to the question: How should meiosis be taught. This book proposes answers to these questions, with extensive supporting references to the current literature. At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? Found insideAs reproductive health is a fundamental component of an individual’s overall health status and a central determinant of quality of life, this book provides the most extensive and authoritative reference within the field.

Each section of the book includes an introduction based on the AP® curriculum and includes rich features that engage students in scientific practice and AP® test preparation; it also highlights careers and research opportunities in ... The book discusses meiosis with regard to the meiotic behavior of chromosomes; the anomalous meiotic behavior in organisms with localized centromeres and in forms with nonlocalized centromeres; and the nature of the synaptic force. Physiological reproduction; mitotic rhythms and experimental synchronization; and the blockage and stimulation of division are also encompassed. Biologists, microbiologists, zoologists, and botanists will find the book invaluable. Found insideThis is the first edition of the book so it covers the introductory level of topics which are ideal for veterinary students, classroom use, and practitioners who require more guidance with genetics. Stem Cells in Reproductive Medicine is essential reading for those keeping abreast of practical developments in this rapidly moving field. Found inside – Page 59In meiosis , only half as many chromosomes have migrated poleward as in mitosis . ... The two daughter cells formed in first telophase of meiosis are haploid since they contain only half the number of chromosomes of the parent cell . In mitosis ... The book discusses meiosis with regard to the meiotic behavior of chromosomes; the anomalous meiotic behavior in organisms with localized centromeres and in forms with nonlocalized centromeres; and the nature of the synaptic force. Found insideThere has recently been a flurry of research activity in this area and this volume summarizes the advances coming from this work. All authors are recognized and respected research scientists at the forefront of research in meiosis. Found insideThis book brings together genetics, reproductive biology and medicine for an integrative view of the emerging specialism of reproductive genetics. Found insideThis book provides an overview of the stages of the eukaryotic cell cycle, concentrating specifically on cell division for development and maintenance of the human body. Found insideCurrently, there are no comprehensive books covering the field of human reproductive and prenatal genetics. As such, this book aims to be among the largest and most useful references available.
