Genomics is an interdisciplinary field of biology that delves into the structure, mapping, evolution, function and editing of genomes. It aims at the collective quantification and characterization of genes. This is done through the analysis and sequencing of genomes with the aid of high throughput DNA sequencing and bioinformatics. The studies of intragenomic phenomena like pleiotropy, heterosis, epistasis and other interactions between alleles and loci within the genome are also within the purview of this field. Genomics plays a crucial role in the fields of anthropology, medicine, biotechnology and other sciences. Metagenomics, functional genomics, structural genomics, epigenomics and model systems are the primary areas of research in genomics. This book includes some of the vital pieces of work being conducted across the world, on various topics related to genomics. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. This book is appropriate for students seeking detailed information in this area as well as for experts.
