Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Evolution and Selection of Quantitative Traits

Evolution and Selection of Quantitative Traits PDF Author: Bruce Walsh
Publisher: Oxford University Press
ISBN: 0192566644
Category : Science
Languages : en
Pages : 1504

Book Description
Quantitative traits-be they morphological or physiological characters, aspects of behavior, or genome-level features such as the amount of RNA or protein expression for a specific gene-usually show considerable variation within and among populations. Quantitative genetics, also referred to as the genetics of complex traits, is the study of such characters and is based on mathematical models of evolution in which many genes influence the trait and in which non-genetic factors may also be important. Evolution and Selection of Quantitative Traits presents a holistic treatment of the subject, showing the interplay between theory and data with extensive discussions on statistical issues relating to the estimation of the biologically relevant parameters for these models. Quantitative genetics is viewed as the bridge between complex mathematical models of trait evolution and real-world data, and the authors have clearly framed their treatment as such. This is the second volume in a planned trilogy that summarizes the modern field of quantitative genetics, informed by empirical observations from wide-ranging fields (agriculture, evolution, ecology, and human biology) as well as population genetics, statistical theory, mathematical modeling, genetics, and genomics. Whilst volume 1 (1998) dealt with the genetics of such traits, the main focus of volume 2 is on their evolution, with a special emphasis on detecting selection (ranging from the use of genomic and historical data through to ecological field data) and examining its consequences.

Book Description
Gegenstand dieser Arbeit ist es, den Einsatz der genomischen Zuchtwertschätzung für neue funktionale Merkmale und den Gehalt an Milchinhaltsstoffen auf Ebene der einzelnen Euterviertel in der Milchrinderzucht zu beleuchten. Nach einer allgemeinen Einführung in die genomische Selektion und in das Prinzip der Testherden werden im zweiten Kapitel genetische Parameter und Heritabilitäten für verschiedene Verhaltensmerkmale, für Milchfluss, Eutertiefe, Labienlage und Tage bis zur 1. Brunst geschätzt. Im dritten Kapitel erfolgt eine Schätzung genetischer Parameter und Heritabilitäten für die Milchinhaltsstoffe (Fett, Eiweiß, Lactose, Harnstoff, SCS) und für Hyperkeratosen der Zitzen auf Basis der einzelnen Euterviertel. Ferner werden additiv genetische und phänotypische Korrelationen für diese Merkmale zwischen den Eutervierteln geschätzt. Im vierten Kapitel wird eine genomische Zuchtwertschätzung für die funktionalen Merkmale aus Kapitel eins auf Basis von 777k Genotypen vorgestellt. Die Sicherheit der genomischen Zuchtwerte wird zudem mit einem neuen Ansatz abgeleitet, der trotz geringer Sicherheit der konventionellen Zuchtwerte eine realistische Abschätzung der genomischen Zuchtwerte erlaubt. Im fünften Kapitel werden abschließend die Möglichkeiten beleuchtet, eine genomische Zuchtwertschätzung für funktionale Merkmale in einem Testherdensystem zu etablieren.

Pages : 207

Book Description
The subject wise multiple-choice questions by Ink Zone publication for VLDA, LSA, and Veterinary Pharmacy has been designed as per the latest syllabus released by the various universities. The objective of this book is to present a concise collection of important questions of veterinary and animal science, which are frequently asked in All India entrance & competitive examinations. All efforts have been made to include all the questions that had previously been asked in various state competitive exams in the past years. Every chapter includes multiple-choice questions which has been compiled and presented in a coherent manner after going through various previous state competitive exams and the standard books for a particular subject. The effort has been made to enable students to cover the subjects in a short span of time and make the student exam ready. We believe this book would certainly benefit aspirants of State PSC Veterinary Officer, VLDA, LSA, Veterinary Pharmacy exams. Inspite of our best efforts to make this book error free, some minor printing errors might have crept in. We sincerely apologize for the inconvenience. We welcome suggestions for further improvement of the book and the same will be incorporated in our further editions.
