Download or read book Estimation of Genetic Parameters Under Optimal and Suboptimal Environments for Body Weight in Chicken Using a Diallel Mating System written by Mohamed Hanafi Sayed Mahmoud and published by . This book was released on 1966 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2 x 2 x 2N confounded diallel mating design (2 series, 2 males, N females per male per series) was used to obtain estimates of the genetic parameters in body weight traits in a noninbred population of New Hampshire chickens grown on 18% and 24% protein rations. Individual selection also was applied to evaluate the reliability of the genetic parameters obtained under each protein level. The analysis showed an extremely large contribution of series effects to the total variation in the traits which was attributed to the environmental influences from one series to the other and to the maternal environment. The component of variance due to series x male interaction was found to be small or zero under the 24% protein ration. An optimal environment may have given certain genotypes a greater opportunity to adapt to the environment. The higher estimates of the component of variance of series x female interaction for one-day body weight suggests the influence of maternal effects from one series to the other and from one dam to the other. Generally, estimates for the component of variance of male effects were higher under the 18% protein ration than under the 24% protein ration. Conversely, the component of variance of female effects showed higher values under the 24% protein ration than under 18% protein ration for most of the traits considered. ...

Available in PDF, EPUB and Kindle. Book excerpt: With contributions by internationally reputed researchers in the field, this book presents the implications of the genomic revolution for conifers—promoting a better understanding of the evolution of these organisms as well as new knowledge about the molecular basis of quantitative trait variation. Both of these discoveries play important roles in their domestication. Topics include cytogenetics, patterns of nucleotide diversity, genetic mapping, integration of molecular markers in breeding, transcriptomics, advances in proteomics and metabolomics in gymnosperms, and economic importance.

Book excerpt: The properties of continuous variation are basic to the theory of evolution and to the practice of plant and animal improvement. Yet the genetical study of continuous variation has lagged far behind that of discontinuous variation. The reason for this situation is basically methodological. Mendel gave us not merely his principles of heredity, but also a method of experiment by which these principles could be tested over a wider range of living species, and extended into the elaborate genetical theory of today. The power of this tool is well attested by the speed with which genetics has grown. In less than fifty years, it has not only developed a theoretical structure which is unique in the biological sciences, but has established a union with nuclear cytology so close that the two have become virtually a single science offering us a new approach to problems so diverse as those of evolution, development, disease, cellular chemistry and human welfare. Much of this progress would have been impossible and all would have been slower without the Mendelian method of recognizing and using unit differences in the genetic materials.

Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic addresses research in genomics and biotechnology to improve the growth and quality of forest trees for wood, pulp, biorefineries and carbon capture. Forests are the world’s greatest repository of terrestrial biomass and biodiversity. Forests serve critical ecological services, supporting the preservation of fauna and flora, and water resources. Planted forests also offer a renewable source of timber, for pulp and paper production, and the biorefinery. Despite their fundamental role for society, thousands of hectares of forests are lost annually due to deforestation, pests, pathogens and urban development. As a consequence, there is an increasing need to develop trees that are more productive under lower inputs, while understanding how they adapt to the environment and respond to biotic and abiotic stress. Forest genomics and biotechnology, disciplines that study the genetic composition of trees and the methods required to modify them, began over a quarter of a century ago with the development of the first genetic maps and establishment of early methods of genetic transformation. Since then, genomics and biotechnology have impacted all research areas of forestry. Genome analyses of tree populations have uncovered genes involved in adaptation and response to biotic and abiotic stress. Genes that regulate growth and development have been identified, and in many cases their mechanisms of action have been described. Genetic transformation is now widely used to understand the roles of genes and to develop germplasm that is more suitable for commercial tree plantations. However, in contrast to many annual crops that have benefited from centuries of domestication and extensive genomic and biotechnology research, in forestry the field is still in its infancy. Thus, tremendous opportunities remain unexplored. This Research Topic aims to briefly summarize recent findings, to discuss long-term goals and to think ahead about future developments and how this can be applied to improve growth and quality of forest trees.
