Pre-Publication Draft The Early History of Medical Genetics in Canada Abstract: This article shows that the intellectual and specialist movements that supported the growth of medical genetics in Canada between 1947 and 1990 were emergent phenomena, created, split, and reattached to different groups of actors, and reconfigured numerous times over the course of four decades. In each instance, new kinds of working relationships appeared; sets of diverse actors in local university- hospital settings coalesced into a new collectivity; and, as a collectivity, actors defined and/or redefined occupational roles and work rules. In its beginnings, medical genetics appears to be the object of a serious institutional manoeuver: a movement in support of the creation of examining and teaching positions in human genetics in North American medical schools. With time, the institutionalization of ‘medical genetics’ took hold, spurred on by changes in the rate and direction of service delivery associated with genetic consultation and laboratory services in clinical settings. -
Part I April 1952
HEREDITY VOLUME 6 PART I APRIL 1952 STATISTICALMETHODS IN GENETICS R. A. FISHER Being the Bateson Lecture delivered at the John lnnes Horticultural Institution on Friday, 6th July 1951 * THEtitle chosen for this lecture is "StatisticalMethods in Genetics," but after hearing what I have written you may think that it is not so much an account of the contributions which the study of Statistics has made to the advance of Genetics, as an examination of the nature of genetical Science from the point of view of a statistician,. My reason for taking this point of view is that for many active years of my life I was fully engaged in doing what I could to further the progress of statistical methods, and that though for 25 years or so I have enjoyed the excitements of genetic experimentation, Genetics has only gradually come to be, for me, a whole time study, in place of a very fascinating hobby. Since that experience is in itself exceptional, it may be that the refiexions gathered on the way are worthy of record, and of interest to my genetical colleagues. Genetics and Statistics have in common that they are both characteristic products of the twentieth century. As we should recognise them now, neither of them existed before the year 1900. Of course I do not ignore the fact that earlier workers of many nations, Naudin and Godron, for example, Knight, Gaertner and Kohlreuter broached the practical problems of experimentation in heredity, or that on the theoretical side Galton and Weismann put forward speculations sometimes to an interesting extent near the truth. -
The Practical Mendelism of Erich Tschermak
From a draft. May differ from the published version, which appeared in New Perspectives on the History of Life Sciences and Agriculture, ed. Denise Phillips and Sharon E. Kingsland, 419–439, Springer-Verlag, 2015. Breeding Better Peas, Pumpkins, and Peasants: The Practical Mendelism of Erich Tschermak SANDER GLIBOFF Indiana University Abstract. This paper follows the career of Erich Tschermak (1871–1962, aka Erich von Tschermak-Seysenegg), one of the three “co-rediscoverers” of Mendel’s laws. It considers the practical ramifications, in agricul- ture, eugenics, and politics, of Tschermak’s reading of Mendel’s theory, and examines how Tschermak promoted his theories and practices—and himself—in the shifting contexts of the Austro-Hungaian Empire, Aus- trian First Republic, and Nazi period. Special attention is given to the hybridization work on peas that led him to Mendel’s paper, to the devel- opment of the “Tschermak Pumpkin” in the 1930s as an illustration of the practical side of his Mendelism, and to his wartime consultations with the German Minister of Agriculture on selecting and crossing strains of crops, animals, and even the peasants to go with them to planned settlements in occupied Poland and Ukraine. Keywords: Genetics, Mendelism, Plant Breeding, Eugenics, Hybridization, Erich von Tschermak-Seysenegg, Biography, Austria, Early 20th Century. Introduction The historiography of Mendelism and early genetics has taken a practical turn in recent years. From the context of sheep breeding in pre-Mendelian Moravia and Mendel’s own involvement in scientific agriculture and plant breeding1 to the 1.

It is the reason why offspring look like their parents. It also explains why cats always give birth to kittens and never puppies. The process of heredity occurs among all living organisms, including animals, plants, bacteria, protists and fungi. Genetic variation refers to the variation in a population or species. Genetics is the study of heredity and variation in living organisms. Two research approaches were historically important in helping investigators understand the biological basis of heredity. The first of these approaches, ‘transmission genetics’, involved crossing organisms and studying the offsprings' traits to develop hypotheses about the mechanisms of inheritance. The second approach involved using cytological techniques to study the machinery and processes of cellular reproduction. This approach laid a solid foundation for the more conceptual understanding of inheritance that developed as a result of transmission genetics. Ever since 1970s, with the advent of molecular tools and techniques, geneticists are able to intensively analyze genetic basis of trait variation in various organisms, including plants, animals and humans. -

J. Genet. Plant Breed., 49: 90–94. Breeding wheat with blue grain was conducted at the Crop Research Institute in Prague. Initial donor material came from the legacy of Erich von Tschermak-Seysenegg. Long-term crosses with a series of winter wheat varie- ties were made with the aim of transferring blue grain colour into cultivated varieties. The prospective mate- rial was later handed over to Agrotest Fyto, Ltd., Kroměříž, where line no. 6 was selected from the population RU 440. At the end of 2011, the new winter wheat variety Skorpion with blue grain was registered in Austria. It is intended for special use in the food industry. The anthocyanins which it contains are considered to offer health benefits due to their antioxidant effects. Keywords: agronomic traits; anthocyanins; blue aleurone; grain quality; new variety; Triticum aestivum L. In 2011, after 3 years of testing (2009–2011), phenolic compounds, especially tannins, which the winter wheat variety Skorpion was registered positively affect resistance in wheat to sprouting in Austria. In 2012, it was then enrolled in the (Himi & Noda 2004). -

The Third Base
Appendix The Third Base Donald Forsdyke If I thought that by learning more and more I should ever arrive at the knowledge of absolute truth, I would leave off studying. But I believe I am pretty safe. Samuel Butler, Notebooks Darwin’s mentor, the geologist Charles Lyell, and Darwin himself, both con- sidered the relationship between the evolution of biological species and the evolution of languages [1]. But neither took the subject to the deep informa- tional level of Butler and Hering. In the twentieth century the emergence of a new science – Evolutionary Bioinformatics (EB) – was heralded by two dis- coveries. First, that DNA – a linear polymer of four base units – was the chromosomal component conveying hereditary information. Second, that much of this information was “a phenomenon of arrangement” – determined by the sequence of the four bases. We conclude with a brief sketch of the new work as it relates to William Bateson’s evolutionary ideas. However, imbued with true Batesonian caution (“I will believe when I must”), it is relegated to an Appendix to indicate its provisional nature. Modern languages have similarities that indicate branching evolution from common ancestral languages [2]. We recognize early variations within a language as dialects or accents. When accents are incompatible, communi- cation is impaired. As accents get more disparate, mutual comprehension de- creases and at some point, when comprehension is largely lost, we declare that there are two languages where there was initially one. The origin of lan- guage begins with differences in accent. If we understand how differences in accent arise, then we may come to understand something fundamental about the origin of language (and hence of a text written in that language). -
Statement About Pnas Paper “The New Mutation Theory of Phenotypic Evolution”
July 30, 2007 (revised) Brief Historical Perspectives of the Paper “THE NEW MUTATION THEORY OF PHENOTYPIC EVOLUTION” Proceedings of the National Academy of Sciences, USA, 104:12235-12242, Published July 17, 2007 online. Masatoshi Nei The following is the author’s account of the history of development of the mutation theory of phenotypic evolution and related matters. Darwinism (1) Charles Darwin proposed that evolution occurs by natural selection in the presence of fluctuating variation. (2) At his time, the mechanism of generation of new variation was not known, and he assumed that new variation is generated by climatic changes, inheritance of acquired characters, spontaneous variations, etc. However, he believed that new variation occurs in random direction and evolutionary change is caused by natural selection. (3) He assumed that enormous phenotypic diversity among different phyla and classes is the result of accumulation of gradual evolution by natural selection. Saltationism Several biologists such as Thomas Huxley, William Bateson, and Hugo de Vries argued that the extent of variation between species is much greater than that within 1 species and therefore saltational or macromutational change is necessary to form new species rather than gradual evolution as proposed by Darwin. In this view a new species can be produced by a single macromutation, and therefore natural selection is unimportant. This view was strengthened when de Vries discovered several new forms of evening primroses which were very different from the parental species (Oenothera lamarckiana) and appeared to be new species. This discovery suggested that new species can arise by a single step of macromutation. However, it was later shown that O. -

Chromosomes in the Clinic: The Visual Localization and Analysis of Genetic Disease in the Human Genome Abstract This dissertation examines the visual cultures of postwar biomedicine, with a particular focus on how various techniques, conventions, and professional norms have shaped the `look', classification, diagnosis, and understanding of genetic diseases. Many scholars have previously highlighted the `informational' approaches of postwar genetics, which treat the human genome as an expansive data set comprised of three billion DNA nucleotides. Since the 1950s however, clinicians and genetics researchers have largely interacted with the human genome at the microscopically visible level of chromosomes. Mindful of this, my dissertation examines -

INTRODUCTION TO GENETICS Table of Contents Heredity, historical perspectives | The Monk and his peas | Principle of segregation Dihybrid Crosses | Mutations | Genetic Terms | Links Heredity, Historical Perspective | Back to Top For much of human history people were unaware of the scientific details of how babies were conceived and how heredity worked. Clearly they were conceived, and clearly there was some hereditary connection between parents and children, but the mechanisms were not readily apparent. The Greek philosophers had a variety of ideas: Theophrastus proposed that male flowers caused female flowers to ripen; Hippocrates speculated that "seeds" were produced by various body parts and transmitted to offspring at the time of conception, and Aristotle thought that male and female semen mixed at conception. Aeschylus, in 458 BC, proposed the male as the parent, with the female as a "nurse for the young life sown within her". During the 1700s, Dutch microscopist Anton van Leeuwenhoek (1632-1723) discovered "animalcules" in the sperm of humans and other animals. Some scientists speculated they saw a "little man" (homunculus) inside each sperm. These scientists formed a school of thought known as the "spermists". They contended the only contributions of the female to the next generation were the womb in which the homunculus grew, and prenatal influences of the womb. An opposing school of thought, the ovists, believed that the future human was in the egg, and that sperm merely stimulated the growth of the egg. Ovists thought women carried eggs containing boy and girl children, and that the gender of the offspring was determined well before conception. -

DIVISION OF THE HUMANITIES AND SOCIAL SCIENCES CALIFORNIA INSTITUTE OF TECHNOLOGY PASADENA, CALIFORNIA 91125 GENETICS IN THE UNITED STATES AND GREAT BRITAIN 1890 to 1930: QUERIES AND SPECULATIONS Daniel J. Kev1es HUMANITIES WORKING PAPER 15 December 1978 According to recent scholarship in the early history of genetics, by the l890s many younger biologists were growing restless with phylogenetic morphology and embryology, the traditional descriptive approaches to the much-debated problems of evolutionary theory. Eager to break away from these approaches, a number of these biologists -- and some older ones such as Alfred R. Wallace called for programs of experimental research in evolution addressed in particular to the problems of heredity and variation. "No problems in the whole range of biology," Charles O. Whitman of Woods Hole typically said, were of 1 "higher scientific interest or deeper practical import to humanity." In England Francis Galton inspired one of the more important experimental research programs -- W. F. R. Weldon's statistical analyses, developed in collaboration with Karl Pearson, of variations in large populations. Another important departure was the program of hybridization experiments exemplified in the research of William Bateson. Pearson and Weldon helped establish the field of heredity studies known as biometry. The research of Bateson and others paved the way for the rediscovery in 2 1900 and then vigorous advocacy of the Mendelian paradigm. Mendel's ideas did not gain rapid acceptance in all biological quarters in either the United States or Great Britain, In England, the biometricians Weldon and Pearson hotly disputed the validity of Mendel's results, the merits of his conceptual scheme, and even the integrity of his British advocates, especially Bateson. -
