Book Description
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).

Book Description
In the small “Fly Room†at Columbia University, T.H. Morgan and his students, A.H. Sturtevant, C.B. Bridges, and H.J. Muller, carried out the work that laid the foundations of modern, chromosomal genetics. The excitement of those times, when the whole field of genetics was being created, is captured in this book, written in 1965 by one of those present at the beginning. His account is one of the few authoritative, analytic works on the early history of genetics. This attractive reprint is accompanied by a website, http://www.esp.org/books/sturt/history/ offering full-text versions of the key papers discussed in the book, including the world's first genetic map.

Book Description
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).

Book Description
The Foundations of Genetics describes the historical development of genetics with emphasis on the contributions to advancing genetical knowledge and the various applications of genetics. The book reviews the work of Gregor Mendel, his Law of Segregation, and of Ernst Haeckel who suggested that the nucleus is that part of the cell that is responsible for heredity. The text also describes the studies of W. Johannsen on "pure lines," and his introduction of the terms gene, genotype, and phenotype. The book explains the theory of the gene and the notion that hereditary particles are borne by the chromosomes (Sutton-Boveri hypothesis). Of the constituent parts of the nucleus only the chromatin material divides at mitosis and segregates during maturation. Following studies confirm that the chromatin material, present in the form of chromosomes with a constant and characteristic number and appearance for each species, is indeed the hereditary material. The book describes how Muller in 1927, showed that high precision energy radiation is the external cause to mutation in the gene itself if one allele can mutate without affecting its partner. The superstructure of genetics built upon the foundations of Mendelism has many applications including cytogenetics, polyploidy, human genetics, eugenics, plant breeding, radiation genetics, and the evolution theory. The book can be useful to academicians and investigators in the fields of genetics such as biochemical, biometrical, microbial, and pharmacogenetics. Students in agriculture, anthropology, botany, medicine, sociology, veterinary medicine, and zoology should add this text to their list of primary reading materials.

Book Description
John Waller describes the changing ideas concerning heredity from antiquity to the modern biological understanding, considering both the efforts over the centuries to identify the physiological mechanisms involved and how views of heredity have been used to justify or condemn inequalities of class, gender, and race.

Book Description
Six years after Charles Darwin announced his theory of evolution to the world, Gregor Mendel began studying the inheritance of traits in pea plants. Mendel's research led to his discovery of dominant and recessive traits and other facts of evolution, which he reported in his groundbreaking 1865 paper, Experiments in Plant Hybridization. His findings languished until 1902, when William Bateson revived interest in the subject with this book, a succinct account of Mendel's heredity-related discoveries. Bateson coined the term "genetics" to refer to heredity and inherited traits, and his rediscovery of Mendel's work forms the foundation of today's field of genetics. Suitable for biology and general science students at the undergraduate and graduate levels, this volume is essential reading for anyone with an interest in science and genetics. In addition to Bateson's commentary, it features two of Mendel's papers—including the original Experiments—plus a biography of Mendel, a detailed bibliography, and indexes of subjects and authors. Numerous figures complement the text, along with eight pages of color illustrations.

Book Description
"In the early 1800s, a century before there was any concept of the gene, physicians in insane asylums began to record causes of madness in their admission books. Almost from the beginning, they pointed to heredity as the most important of these causes. As doctors and state officials steadily lost faith in the capacity of asylum care to stem the terrible increase of insanity, they began emphasizing the need to curb the reproduction of the insane. They became obsessed with identifying weak or tainted families and anticipating the outcomes of their marriages. Genetics in the Madhouse is the untold story of how the collection and sorting of hereditary data in mental hospitals, schools for 'feebleminded' children, and prisons gave rise to a new science of human heredity. In this compelling book, Theodore Porter draws on untapped archival evidence from across Europe and North America to bring to light the hidden history behind modern genetics. He looks at the institutional use of pedigree charts, censuses of mental illness, medical-social surveys, and other data techniques--innovative quantitative practices that were worked out in the madhouse long before the manipulation of DNA became possible in the lab. Porter argues that asylum doctors developed many of the ideologies and methods of what would come to be known as eugenics, and deepens our appreciation of the moral issues at stake in data work conducted on the border of subjectivity and science. A bold rethinking of asylum work, Genetics in the Madhouse shows how heredity was a human science as well as a medical and biological one"--Jacket.

Book Description
If not for the work of his half cousin Francis Galton, Charles Darwin's evolutionary theory might have met a somewhat different fate. In particular, with no direct evidence of natural selection and no convincing theory of heredity to explain it, Darwin needed a mathematical explanation of variability and heredity. Galton's work in biometry—the application of statistical methods to the biological sciences—laid the foundations for precisely that. This book offers readers a compelling portrait of Galton as the "father of biometry," tracing the development of his ideas and his accomplishments, and placing them in their scientific context. Though Michael Bulmer introduces readers to the curious facts of Galton's life—as an explorer, as a polymath and member of the Victorian intellectual aristocracy, and as a proponent of eugenics—his chief concern is with Galton's pioneering studies of heredity, in the course of which he invented the statistical tools of regression and correlation. Bulmer describes Galton's early ambitions and experiments—his investigations of problems of evolutionary importance (such as the evolution of gregariousness and the function of sex), and his movement from the development of a physiological theory to a purely statistical theory of heredity, based on the properties of the normal distribution. This work, culminating in the law of ancestral heredity, also put Galton at the heart of the bitter conflict between the "ancestrians" and the "Mendelians" after the rediscovery of Mendelism in 1900. A graceful writer and an expert biometrician, Bulmer details the eventual triumph of biometrical methods in the history of quantitative genetics based on Mendelian principles, which underpins our understanding of evolution today.
