The book "Molecular Genetics in Animal Breeding" is a comprehensive guide that covers both basic and advanced concepts in the field. The main focus of the book is to provide a thorough understanding of molecular genetics and its applications in animal breeding.The introductory section of the book discusses the significance of molecular genetics in animal breeding. The basics of genetics, including genome organization and the current status of genome maps of livestock, are covered. The book also provides an overview of various molecular markers, such as RFLP, RAPD, microsatellite/minisatellite markers, SNP markers, and DNA fingerprinting.The book then moves on to more advanced topics, such as DNA sequencing, genome sequencing, genomic library, and PCR techniques. Transgenesis and methods of gene transfer are also discussed. Additionally, the book includes a detailed discussion of statistical techniques for analyzing molecular genetic data, QTL mapping, genome scan, candidate gene approach, genomic selection, and marker-assisted selection.The book is especially useful for students and professionals who are preparing for entrance exams like ICAR-SRF, ARS, and other competitive exams in the field of animal breeding. Overall, this book is a valuable resource for anyone interested in the field of molecular genetics in animal breeding, from students and researchers to professionals and industry practitioners.
