This book was released on 2012-12-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by the leading experts in the field, this book examines the evolutionary advantages of gender dimorphism and sexual dimorphism in flowering plants. Divided into three sections: the first introduces readers to the tremendous variety of breeding systems and their evolution in plants and sets the stage for a consideration of the evolution of dimorphism in reproductive and non-reproductive characters. The second section deals with the evolution of secondary sexual characters, including the theory related to the evolution of sexual dimorphism and its empirical patterns, while the last section deals with the genetics of gender expression and of secondary sexual characters.

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 Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. 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 self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
