Adaptation and Fitness in Animal Populations
Evolutionary and Breeding Perspectives on Genetic Resource Management
AvJulius van der Werf,Hans-Ulrich Graserm. fl.

Skickas inom 10-15 vardagar
Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production.Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use.Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources.This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

Genome-Wide Association Studies and Genomic Prediction
AvCedric Gondro,Julius van der Werfm. fl.

With the detailed genomic information that is now becoming available, we have a plethora of data that allows researchers to address questions in a variety of areas. Genome-wide association studies (GWAS) have become a vital approach to identify candidate regions associated with complex diseases in human medicine, production traits in agriculture, and variation in wild populations. Genomic prediction goes a step further, attempting to predict phenotypic variation in these traits from genomic information. Genome-Wide Association Studies and Genomic Prediction pulls together expert contributions to address this important area of study. The volume begins with a section covering the phenotypes of interest as well as design issues for GWAS, then moves on to discuss efficient computational methods to store and handle large datasets, quality control measures, phasing, haplotype inference, and imputation. Later chapters deal with statistical approaches to data analysis where the experimental objective is either to confirm the biology by identifying genomic regions associated to a trait or to use the data to make genomic predictions about a future phenotypic outcome (e.g. predict onset of disease). As part of the Methods in Molecular Biology series, chapters provide helpful, real-world implementation advice.

Del 72 - Burleigh Dodds Series in Agricultural Science
Advances in Breeding of Dairy Cattle

This collection reviews the latest research on dairy cattle genetics and advanced methods of genetic evaluation and selection. After an overview of genetic improvements achieved so far, Part 1 assesses the problem of inbreeding and genetic diversity in modern dairy cattle as well as opportunities for crossbreeding. Part 2 then goes onto review research on targeting non-production traits such as fertility, feed conversion efficiency and methane emissions as well as resistance to disease and resilience to heat stress. Part 3 then surveys the latest techniques and advances in genomic selection (GS) in such areas as functional annotation and use of sequence variants to improve genomic prediction, as well as developments in genetic evaluation (GE). The final part of the book reviews developments in embryo technologies, gene editing and the way new techniques are being integrated in practice into dairy breeding programmes.
