Experiments in Plant Hybridisation by Gregor Mendel Pdf

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).

Ending the Mendel-Fisher Controversy by Allan Franklin,A. W. F. Edwards,Daniel J. Fairbanks,Daniel L. Hartl Pdf

In 1865, Gregor Mendel presented "Experiments in Plant-Hybridization," the results of his eight-year study of the principles of inheritance through experimentation with pea plants. Overlooked in its day, Mendel's work would later become the foundation of modern genetics. Did his pioneering research follow the rigors of real scientific inquiry, or was Mendel's data too good to be true-the product of doctored statistics? In Ending the Mendel-Fisher Controversy, leading experts present their conclusions on the legendary controversy surrounding the challenge to Mendel's findings by British statistician and biologist R. A. Fisher. In his 1936 paper "Has Mendel's Work Been Rediscovered?" Fisher suggested that Mendel's data could have been falsified in order to support his expectations. Fisher attributed the falsification to an unknown assistant of Mendel's. At the time, Fisher's criticism did not receive wide attention. Yet beginning in 1964, about the time of the centenary of Mendel's paper, scholars began to publicly discuss whether Fisher had successfully proven that Mendel's data was falsified. Since that time, numerous articles, letters, and comments have been published on the controversy. This self-contained volume includes everything the reader will need to know about the subject: an overview of the controversy; the original papers of Mendel and Fisher; four of the most important papers on the debate; and new updates, by the authors, of the latter four papers. Taken together, the authors contend, these voices argue for an end to the controversy-making this book the definitive last word on the subject.

Racism in America by Harvard University Press Pdf

Racism in America has been the subject of serious scholarship for decades. At Harvard University Press, we’ve had the honor of publishing some of the most influential books on the subject. The excerpts in this volume—culled from works of history, law, sociology, medicine, economics, critical theory, philosophy, art, and literature—are an invitation to understand anti-Black racism through the eyes of our most incisive commentators. Readers will find such classic selections as Toni Morrison’s description of the Africanist presence in the White American literary imagination, Walter Johnson’s depiction of the nation’s largest slave market, and Stuart Hall’s theorization of the relationship between race and nationhood. More recent voices include Khalil Gibran Muhammad on the pernicious myth of Black criminality, Elizabeth Hinton on the link between mass incarceration and 1960s social welfare programs, Anthony Abraham Jack on how elite institutions continue to fail first-generation college students, Mehrsa Baradaran on the racial wealth gap, Nicole Fleetwood on carceral art, and Joshua Bennett on the anti-Black bias implicit in how we talk about animals and the environment. Because the experiences of non-White people are integral to the history of racism and often bound up in the story of Black Americans, we have included writers who focus on the struggles of Native Americans, Latinos, and Asians as well. Racism in America is for all curious readers, teachers, and students who wish to discover for themselves the complex and rewarding intellectual work that has sustained our national conversation on race and will continue to guide us in future years.

Experiments in Plant Hybridization: The Genetic Heredity Demonstrated by Hybrids of Garden Peas by Gregor Mendel Pdf

Mendel's groundbreaking paper, which laid the foundation for further research upon heritage and genetics, is published here complete with the original illustrations and charts. When Mendel released this paper in 1865, it was after years of rigorous study and comparison in plant specimens and their offspring. His conclusion that variant traits were hereditary and could be determined, with a good degree of accuracy, through probability analysis were revolutionary in natural science at the time. Mendel's assertions regarding acquired characteristics, demonstrated through the comparison of peas and their seeds, would spark great interest in the nature and mechanisms behind heredity between generations of organisms. Seeking to gain high quality results, Mendel prefaces his explanations by noting that he artificially fertilized the plants described in the work.

Concepts of Biology by Samantha Fowler,Rebecca Roush,James Wise Pdf

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

The Monk in the Garden by Robin Marantz Henig Pdf

This acclaimed biography of 19th century scientist Gregor Mendel is “a fascinating tale of the strange twists and ironies of scientific progress” (Publishers Weekly). A National Book Critics Circle Award finalist In The Monk in the Garden, award-winning author Robin Marantz Henig vividly chronicles the birth of genetics, a field that continues to challenge the way we think about life itself. Tending to his pea plants in a monastery garden, the Moravian monk Gregor Mendel discovered the foundational principles of genetic inheritance. But Mendel’s work was ignored during his lifetime, even though it answered the most pressing questions raised by Charles Darwin's revolutionary book, On the Origin of Species. Thirty-five years after his death, Mendel’s work was saved from obscurity when three scientists from three different countries nearly simultaneously dusted off his groundbreaking paper and finally recognized its profound significance. From the perplexing silence that greeted his discovery to his ultimate canonization as the father of genetics, Henig presents a tale filled with intrigue, jealousy, and a healthy dose of bad timing. Though little is known about Mendel’s life, she "has done a remarkable job of fleshing out the myth with what few facts there are" (Washington Post Book World).
