The “Refresher Book on Animal Genetics and Breeding” by Dr. Asit Jain, Dr. Mohan Singh Thakur, Dr. Akansha Singh, Dr. Vaishali Khare, and Dr. Tripti Jain serves as a comprehensive objective-based guide for students and professionals in Veterinary Science and Animal Husbandry. Structured to meet the academic and competitive examination needs of undergraduate (B.V.Sc. & A.H.), post-graduate (M.V.Sc./M.Sc.), and doctoral scholars, the book covers key areas including biostatistics, genetics, selection, breeding, and breeding of pet, laboratory, and wild animals. Each chapter begins with a concise conceptual overview followed by extensive Multiple Choice Questions (MCQs) and objective-type exercises, offering a unique blend of theoretical insight and applied assessment. This dual approach reinforces understanding and facilitates effective self-evaluation. Designed for aspirants of ICAR-JRF/SRF/NET, State PSC, and other competitive examinations, as well as for use in refresher and training courses, this book provides a clear, structured, and practice-oriented resource for mastering the principles and applications of Animal Genetics and Breeding.
