DOWNLOAD EBOOK →This special re-print edition of Sewall Wright's book "Principles of Livestock Breeding" is a short guide to the subject of breeding animals of various types to perfection. Published in 1920 by the US Department of Agriculture this short guide to livestock breeding explores the basics of the common principles that are used to improve livestock and other animals. Topics include The Evolution of Animal Breeding, Reproduction, Details of Hereditary Transmission, Mendelian Heredity in Livestock, Heredity of Form and Function, The Systems of Breeding, Methods of Selection, The Value of Purebreds and more. This will be found to be a valuable resource to breeders of all types of domestic animals who are looking to greatly improve their stock. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface. As a result, some type characters and images might suffer from slight imperfections or minor shadows in the page background.

DOWNLOAD EBOOK →Experiments which in previous years were made with ornamental plants have already afforded evidence that the hybrids, as a rule, are not exactly intermediate between the parental species. With some of the more striking characters, those, for instance, which relate to the form and size of the leaves, the pubescence of the several parts, etc., the intermediate, indeed, is nearly always to be seen; in other cases, however, one of the two parental characters is so preponderant that it is difficult, or quite impossible, to detect the other in the hybrid. from 4. The Forms of the Hybrid One of the most influential and important scientific works ever written, the 1865 paper Experiments in Plant Hybridisation was all but ignored in its day, and its author, Austrian priest and scientist GREGOR JOHANN MENDEL (18221884), died before seeing the dramatic long-term impact of his work, which was rediscovered at the turn of the 20th century and is now considered foundational to modern genetics. A simple, eloquent description of his 18561863 study of the inheritance of traits in pea plantsMendel analyzed 29,000 of themthis is essential reading for biology students and readers of science history. Cosimo presents this compact edition from the 1909 translation by British geneticist WILLIAM BATESON (18611926).

The book is "a concise and accurate narrative, that also manages to be interesting and personal...a splendid little book." Biotechnology states, "Because of the clarity with which it is written, this thin volume makes a major contribution to improving public understanding of genetic engineering's potential for enlarging the world's food supply...and can be profitably read by practically anyone interested in application of molecular biology to improvement of productivity in agriculture."

DOWNLOAD EBOOK →The history of Science is replete with untold stories and this book is one of these accounts. The author shares a narrative of heredity, an active topic of inquiry long before Gregor Mendel – the father of genetics – planted his peas. One such interlude unfolded in Mendel’s home city and involved the sheep breeder, Imre Festetics. He sought to improve wool and proposed important rules of heredity. Unfortunately, aspects of wool quality, now known to be polygenic, complicate interpretations of the work of Festetics and explain why it is neglected. The forebearers of Mendel never get the credit they deserve. Heredity Before Mendel resurrects Festetics, the grandfather of heredity. Key Features 1) Documents a vibrant community of scholars interested in heredity before Mendel 2) Highlights the work of Imre Festetics, the forgotten grandfather of genetics 3) Desribes political repression which stifled the nascent foundation of heredity research 4) Emphasizes the role sheep and wool played as the first model system of genetics 5) Challenges19th century taboos in Moravia leading to malicious rumors about the inbred royal House of Austria (Habsburgs).

DOWNLOAD EBOOK →Animal genetic resource diversity underpins the supply livestock products and services across a wide range of production environments. It promotes resilience and serves as a basis for adapting livestock management to changing conditions. It is vital to livelihoods of many of the world’s poor people. It can contribute to the delivery of ecosystem services such as landscape management and the maintenance of wildlife habitats. However, it is often undervalued, underused and under threat. This report updates the global assessment provided in the first report on The State of the World’s Animal Genetic Resources for Food and Agriculture, published in 2007. It focuses particularly on changes that have occurred during the period since the first report was published. It serves as a basis for a review, and potential update, of the Global Plan of Action for Animal Genetic Resources, which since 2007 has provided an agreed international framework for the management of livestock biodiversity. Drawing on 129 country reports, it presents an analysis of the state of livestock diversity, the influence of livestock-sector trends on the management of animal genetic resources, the state of capacity to manage animal genetic resources, including legal and policy frameworks, and the state of the art in tools and methods for characterization, valuation, use, development and conservation.

How this curious creature and others as humble (and as fast-breeding) have helped unlock the mystery of inheritance is the unlikely story Jim Endersby tells in this book. Biology today promises everything from better foods or cures for common diseases to the alarming prospect of redesigning life itself. Looking at the organisms that have made all this possible gives us a new way of understanding how we got here--and perhaps of thinking about where we're going. Instead of a history of which great scientists had which great ideas, this story of passionflowers and hawkweeds, of zebra fish and viruses, offers a bird's (or rodent's) eye view of the work that makes science possible. Mixing the celebrities of genetics, like the fruit fly, with forgotten players such as the evening primrose, the book follows the unfolding history of biological inheritance from Aristotle's search for the "universal, absolute truth of fishiness" to the apparently absurd speculations of eighteenth-century natural philosophers to the spectacular findings of our day--which may prove to be the absurdities of tomorrow. The result is a quirky, enlightening, and thoroughly engaging perspective on the history of heredity and genetics, tracing the slow, uncertain path--complete with entertaining diversions and dead ends--that led us from the ancient world's understanding of inheritance to modern genetics.
