Genomics is the science that studies the structural, functional and evolutionary aspects of the entire set of genes of an organism. The interdisciplinary study of genetics and genomics investigates the interrelationship between genotypes and phenotypes, and between genes and diseases. It also strives to understand the different genetic variations created by the processes of mutation, natural selection and evolution. The application areas of these fields are spread across a range of industries like pharmaceuticals, crop production, pest control, etc. The various fields and subfields of gene studies along with the recent technological advances have been covered in exhaustive details in this book. Different approaches, evaluations, methodologies and advanced studies on genetics and genomics have been included. Geneticists, students and researchers working in this domain will find it a valuable source of reference.
