Mendels Legacy

This latest book by Elof Carlson (The Unfit) is a first history of classical genetics, the era in which the chromosome theory of heredity was proposed and developed. Highly illustrated and based heavily on early 20th century original sources, the book traces the roots of genetics in breeding analysis and studies of cytology, evolution, and reproductive biology that began in Europe but were synthesized in the United States through new Ph.D. programs and expanded academic funding. Carlson argues that, influenced largely by new technologies and instrumentation, the life sciences progressed though incremental change rather than paradigm shifts, and he describes how molecular biology emerged from the key ideas and model systems of classical genetics. Readable and original, this narrative will interest historians and science educators as well as today's practitioners of genetics.

Gregor Johann Mendel is known as the father of modern genetics. He used cross-breeding to develop different kinds of peas. This allowed him to make predictions about the outcomes. These are now called Mendel's Laws of Heredity. They explain how traits are passed from generation to generation. Mendel also discovered dominant and recessive genes.

Gregor Mendel's discoveries were so far in advance of their day that it wasn't until 50 years had passed that their importance was recognised by the scientific community. Providing an account of scientific history, this work presents the narrative through the work of the life-scientists who built their own research on Mendel's discoveries.

A fascinating, entertaining dive into the long-standing relationship between humans and insects, revealing the surprising ways we depend on these tiny, six-legged creatures. Insects might make us shudder in disgust, but they are also responsible for many of the things we take for granted in our daily lives. When we bite into a shiny apple, listen to the resonant notes of a violin, get dressed, receive a dental implant, or get a manicure, we are the beneficiaries of a vast army of insects. Try as we might to replicate their raw material (silk, shellac, and cochineal, for instance), our artificial substitutes have proven subpar at best, and at worst toxic, ensuring our interdependence with the insect world for the foreseeable future. Drawing on research in laboratory science, agriculture, fashion, and international cuisine, Edward D. Melillo weaves a vibrant world history that illustrates the inextricable and fascinating bonds between humans and insects. Across time, we have not only coexisted with these creatures but have relied on them for, among other things, the key discoveries of modern medical science and the future of the world's food supply. Without insects, entire sectors of global industry would grind to a halt and essential features of modern life would disappear. Here is a beguiling appreciation of the ways in which these creatures have altered--and continue to shape--the very framework of our existence.

How genetics, and the technologies that arise from it, will affect the way we live in the twenty-first centuryIn the mid-nineteenth century, a Moravian friar made a discovery that was to shape not only the future of science but also that of the human race. With his deceptively simple experiments on peas in a monastery garden in Brno, Gregor Mendel was the first to establish the basic laws of heredity, laws from which the principles of modern genetics can be drawn. In this fascinating account, acclaimed science writer Colin Tudge traces the influence on science of Mendel's extraordinary ideas, from the 1850s to the present day, and goes on to ask what might happen in the coming century and beyond.A comprehensive and entertaining work that combines scientific history with a compelling discussion on the future trends of genetic technologies, "The Impact of the Gene" examines how the ideas that underpin the spectrum of all genetic issues are interrelated, and proposes that with a basic understanding of Gregor Mendel's theories and discoveries, all modern genetics falls easily into place. From a monastery garden to the laboratories of the twenty-first century, "The Impact of the Gene" provides a vital overview of the science of genetics, at once "enjoyable and informative . . . readable and entertaining" ("The New York Times Book Review").

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 nine papers in this volume examine the historical experience of particular populations in Western Europe and North America in a search for the processes that change fertility patterns. The contributors' findings enable them to reevaluate some of the conflicting hypotheses that have been advanced for these changes. The authors stress the effects on fertility of changing mortality. Several theoretical discussions emphasize the importance both of the turnover in adult positions due to mortality and of the highly variable life expectancy of children. The empirical analyses consistently reveal strong associations between levels of fertility and mortality. On the other hand, some essays question whether variations in opportunities to marry acted as quite the regulator that Malthus and many after him have thought. In both preindustrial and industrial populations, fertility regulation within marriage emerges as the primary mechanism by which adjustment occurred. Originally published in 1978. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
