Download or read book Theoretical Studies on Sex Ratio Evolution MPB 22 Volume 22 written by Samuel Karlin and published by Princeton University Press. This book was released on 2020-03-31 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a key area of population genetics: the ratio of the sexes in a population, or the allocation of resources to male versus female reproductive function. Samuel Karlin and Sabin Lessard establish the formal theoretical aspects of the evolution of sex ratio within the constraints of genetic mechanisms of sex determination. Their results generalize and unify existing work on the topic, strengthening previous conceptions in some cases and, in other instances, offering new directions of research. There are two main approaches to understanding the causes and effects of sex ratio. One approach focuses on the optimization and adaptive functions of sex allocation, while the other emphasizes the consequences of genetic sex determination mechanisms. In discussing the utility of these two approaches, Professors Karlin and Lessard examine the principal sex-determining mechanisms and facts involved in sex ratio representations, the various genetic and environmental factors that contribute to adaptive sex expression, and the evolution of sex determining systems and controls. From a population genetic perspective, the authors derive evolutionary properties in support of the high incidence of 1:1 sex ratio in natural populations and investigate the conditions that can explain the occurrence of biased sex ratio.

Download or read book The Children of Atomic Bomb Survivors written by National Research Council and published by National Academies Press. This book was released on 1991-02-01 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do persons exposed to radiation suffer genetic effects that threaten their yet-to-be-born children? Researchers are concluding that the genetic risks of radiation are less than previously thought. This finding is explored in this volume about the children of atomic bomb survivors in Hiroshima and Nagasakiâ€"the population that can provide the greatest insight into this critical issue. Assembled here for the first time are papers representing more than 40 years of research. These documents reveal key results related to radiation's effects on pregnancy termination, sex ratio, congenital defects, and early mortality of children. Edited by two of the principal architects of the studies, J. V. Neel and W. J. Schull, the volume also offers an important comparison with studies of the genetic effects of radiation on mice. The wealth of technical details will be immediately useful to geneticists and other specialists. Policymakers will be interested in the overall conclusions and discussion of future studies.
Download or read book The Theory of Sex Allocation MPB 18 Volume 18 written by Eric L. Charnov and published by Princeton University Press. This book was released on 2020-03-31 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive treatment of sex allocation from the standpoint of modern evolutionary theory. It shows how the determination of sex ratio, resource allocation to sperm versus egg within simultaneous hermaphroditism, and the evolution of sex reversal can he explained as examples of a single process. The genetical theory, developed mostly with graphical arguments, also specifies when hermaphroditism and dioecy are themselves evolutionary stable. The work balances theory with field and laboratory research, providing critical tests of the theory by empirical studies of sex ratio in parasitoid wasps and mites, sex reversal in shrimp and coral reef fish, and allocation of resources to pollen versus seeds in higher plants. In addition, the author oilers an encyclopedic review of the field and laboratory work of other scientists, reviews many as yet untested hypotheses in sex allocation, and points toward numerous plant and animal systems that hold promise for future tests.

Download or read book The Descent of Human Sex Ratio at Birth written by Éric Brian and published by Springer Science & Business Media. This book was released on 2007-07-24 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an attempt to renew our links with the oldest traditions of scholarly thinking, but is also a well-tempered reflection on today’s work in objectivization. After a deconstruction of the past and present conditions of scientific understanding of human sex-ratio at birth, the authors propose a reconstruction of the dynamics of the phenomenon based on stochastics. Appendices provide information on the first expression of sex ratio trends, as well as a comparison of Darwin’s treatments of the subject.
Download or read book A Gender Atlas of India written by Radha Kumar and published by . This book was released on 2018 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Gender Atlas of India is a seminal body of work which comprehensively maps and grades India's performance from 2001 to 2016 on issues of concern for women. Taking into account 8 overall indicators and 28 sub-indicators, it looks at how India is performing on various aspects, including sex ratio, women's education, employment, health, political participation and representation; and prevention of crimes against women. Unlike previous attempts, this book examines the change in India's performance over a 15-year period, compares the situation of women in India to that in its neighborhood and internationally, and rates each Indian state and union territory individually. The findings in this book are both provocative and incentivizing for policymakers--they show that where the central and state governments share concerns India's performance on gender has improved, but where they diverge women's condition has deteriorated even further.
Download or read book Maternal Personality Evolution and the Sex Ratio written by Valerie J. Grant and published by Routledge. This book was released on 2006-10-19 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women who are dominant are more likely to have sons. Demographic studies show that more male children are born after wars, yet most people believe that their baby's sex is a matter of chance - determined by the father's sperm. Valerie Grant presents evidence that the mother's personality - which is related to female testosterone levels - can actually influence which type of sperm fertilises the egg. Using data from human and animal studies Valerie Grant discusses the implications for human evolution, developmental psychology and reproductive biology. Her claims are controversial and the implications of her findings far reaching. Whether mothers have sons or daughters may not be a matter of chance. It may depend on which sex infant the mother is more suited to raise.

Download or read book Bare Branches written by Valerie M. Hudson and published by National Geographic Books. This book was released on 2005-09-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: What happens to a society that has too many men? In this provocative book, Valerie Hudson and Andrea den Boer argue that, historically, high male-to-female ratios often trigger domestic and international violence. Most violent crime is committed by young unmarried males who lack stable social bonds. Although there is not always a direct cause-and-effect relationship, these surplus men often play a crucial role in making violence prevalent within society. Governments sometimes respond to this problem by enlisting young surplus males in military campaigns and high-risk public works projects. Countries with high male-to-female ratios also tend to develop authoritarian political systems. Hudson and den Boer suggest that the sex ratios of many Asian countries, particularly China and India—which represent almost 40 percent of the world's population—are being skewed in favor of males on a scale that may be unprecedented in human history. Through offspring sex selection (often in the form of sex-selective abortion and female infanticide), these countries are acquiring a disproportionate number of low-status young adult males, called "bare branches" by the Chinese. Hudson and den Boer argue that this surplus male population in Asia's largest countries threatens domestic stability and international security. The prospects for peace and democracy are dimmed by the growth of bare branches in China and India, and, they maintain, the sex ratios of these countries will have global implications in the twenty-first century.
Download or read book Sex Selection of Children written by Neil G. Bennett and published by Elsevier. This book was released on 2012-12-02 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex Selection of Children explores the strategies used to control the sex of children, the conditions under which a couple would employ a given technique, and the technology to achieve their desired family composition. It also considers the social consequences of sex-selection techniques, the legal factors that might impinge on the use of such a technology, and the ethical considerations associated with its use. Organized into 10 chapters, this book begins with an overview of some of the more humorous past approaches to sex selection. It then discusses the effects of sex selection on fertility, sex selection by means of amniocentesis and selective abortion, and the theorized link between the timing of fertilization and the sex ratio of offspring. A chapter considers a decision-making model that describes the use of sex-selection techniques by couples who wish to have a specific number of children over their entire childbearing period, while another chapter analyzes the economics of sex preference and selection. The remaining chapters address the parental preferences about the sexes of their offspring in different societies, the legal aspects of prenatal sex selection, a moral policy for sex choice, and the ethics and public policy on sex choice. This book is a valuable resource for specialists involved in fields ranging from sociology and economics to biology, public health, law, and ethics.
Download or read book Population and Society written by Dudley L. Poston, Jr and published by Cambridge University Press. This book was released on 2016-12-28 with total page 878 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive yet accessible textbook is an ideal resource for undergraduate and graduate students taking their first course in demography. Clearly explaining technical demographic issues without using extensive mathematics, Population and Society is sociologically oriented, but incorporates a variety of social sciences in its approach, including economics, political science, geography, and history. It highlights the significant impact of decision-making at the individual level - especially regarding fertility, but also mortality and migration - on population change. The text engages students by providing numerous examples of demography's practical applications in their lives, and demonstrates the extent of its relevance by examining a wide selection of data from the United States, Africa, Asia, and Europe. This thoroughly revised edition includes four new chapters, covering topics such as race and sexuality, and encourages students to consider the broad implications of population growth and change for global challenges such as environmental degradation.
Download or read book Sex Allocation written by Stuart West and published by Princeton University Press. This book was released on 2009-09-28 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed an explosion of theoretical and empirical studies of sex allocation, transforming how we understand the allocation of resources to male and female reproduction in vertebrates, invertebrates, protozoa, and plants. In this landmark book, Stuart West synthesizes the vast literature on sex allocation, providing the conceptual framework the field has been lacking and demonstrating how sex-allocation studies can shed light on broader questions in evolutionary and behavioral biology. West clarifies fundamental misconceptions in the application of theory to empirical data. He examines the field's successes and failures, and describes the research areas where much important work is yet to be done. West reveals how a shared underlying theoretical framework unites findings of sex-ratio variation across a huge range of life forms, from malarial parasites and hermaphroditic worms to sex-changing fish and mammals. He shows how research on sex allocation has been central to many critical questions and controversies in evolutionary and behavioral biology, and he argues that sex-allocation research serves as a key testing ground for different theoretical approaches and can help resolve debates about social evolution, parent-offspring conflict, genomic conflict, and levels of selection. Certain to become the defining book on the subject for the next generation of researchers, Sex Allocation explains why the study of sex allocation provides an ideal model system for advancing our understanding of the constraints on adaptation among all living things in the natural world.
