Download or read book Evolution and Selection of Quantitative Traits written by Bruce Walsh and published by Oxford University Press. This book was released on 2018-06-21 with total page 1504 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Likelihood Bayesian and MCMC Methods in Quantitative Genetics written by Daniel Sorensen and published by Springer Science & Business Media. This book was released on 2007-03-22 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, suitable for numerate biologists and for applied statisticians, provides the foundations of likelihood, Bayesian and MCMC methods in the context of genetic analysis of quantitative traits. Although a number of excellent texts in these areas have become available in recent years, the basic ideas and tools are typically described in a technically demanding style and contain much more detail than necessary. Here, an effort has been made to relate biological to statistical parameters throughout, and the book includes extensive examples that illustrate the developing argument.
Download or read book Bioinformatics for Geneticists written by Michael R. Barnes and published by John Wiley & Sons. This book was released on 2003-07-01 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely book illustrates the value of bioinformatics, not simply as a set of tools but rather as a science increasingly essential to navigate and manage the host of information generated by genomics and the availability of completely sequenced genomes. Bioinformatics can be used at all stages of genetics research: to improve study design, to assist in candidate gene identification, to aid data interpretation and management and to shed light on the molecular pathology of disease-causing mutations. Written specifically for geneticists, this book explains the relevance of bioinformatics showing how it may be used to enhance genetic data mining and markedly improve genetic analysis.

Download or read book Breeding for robustness in cattle written by Marija Klopcic and published by BRILL. This book was released on 2023-09-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.

This book was released on 2014-04-08 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
