Book excerpt: Excerpt from Non-Disjunction as Proof of the Chromosome Theory of Heredity There are now about fifty sex-linked mutations known in Drosophila, and the data collected in their investigation are the most extensive known in experimental breeding. The arrangement of the sex-linked genes in a linear series and the establishment of the relative distances between the loci are based upon over half a million flies.4 The work on non disjunction deals directly with the best known of these sex-linked char acters, and therefore rests upon a very firm Mendelian foundation. The inheritance of a recessive sex - linked character may be illustrated by the cross of a vermilion female by a wild type (red - eyed) male (see figure The sons are vermilion - eyed like the mother, and the daugh ters are wild type like the father. This criss - cross inheritance is ex plained by the theory that the genes for the sex - linked characters are carried by the X chromosomes. As shown in figure 2, the son derives his single X chromosome from his mother, and shows vermilion eye color because the gene for vermilion was carried by that chromosome. The Y chromosome from the father does not affect the visible characters of the son in any way. Thus a male always shows by its characters what genes are carried by its X chromosome. The daughter receives from the mother an X carrying the vermilion gene, but since the vermilion is recessive to the unmutated gene (red) carried by the X which she re ceives from the father, she will be wild type (red).

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Mendelism Since the last edition of this little book was pub lished ih [912 the most noteworthy contribution to genetical studies has come from the American school. In the fruit-fly, Drosopkz'la, they have found unusually favourable material with which to work, and they' have exploited the advantages it offers with energy and acumen. Their object has been to connect. The phenomena of heredity with the visible material basis of the chromosomes of the living cell. Indeed, Professor Morgan has declared that, as the result of these researches, the problem of heredity has been solved. While admitting the very high value and interest of the work I am not prepared to subscribe to this dictum. I have tried, however, to present the position of the supporters of the chromosome theory, in order that those who wish to may make themselves acquainted with what is, at the present moment, the most keenly discussed.

Download or read book Classical Genetic Research and Its Legacy written by Benoit Godin and published by Psychology Press. This book was released on 2004 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Governments and researchers from industrial countries have been measuring science and technology for more than seventy years. This book provides an historical examination of official science and technology statistics and indicators in Western countries and addresses the following questions: What were the main historical moments that led to the development of statistics on science and technology? What were the main socio-political stakes behind the activities of science measurement? What were the philosophical and ideological conceptions that drove measurement? What statistics and indicators were developed and how were they constructed? The first part of the book concentrates on the construction and development of science and technology statistics from 1930 to the present, the principles at work, and the vested interests and forces behind that construction. The second part analyzes to what uses statistics were put, and with how much confidence actors used statistics to document their case or to promote their political agenda.
Download or read book A History of Genetics written by Alfred Henry Sturtevant and published by CSHL Press. This book was released on 2001 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Volume 12 is devoted to current and future approaches to insect management and control. The topics discussed cover chemical control, including the use of juvenile hormone analogs, microbiological methods, including viral and fungal agents, biological control, and genetic approaches to insect control. The 20 chapters, all amply referenced and illustrated, well demonstrate the multidisciplinary nature of the subject and the degree of international effort that has led to the present state of knowledge. Fifteen of the chapters are devoted to the action of insecticides, reflecting the immensity of the subject. The past 30 years have witnessed remarkable advances in the scientific basis of insect control and this volume provides a convenient point of entry into the massive amount of literature now available.
