This book features chapter-specific objective questions on a variety of topics in accordance with the syllabi of numerous competitive examinations in the field of Animal Genetics and Breeding. It is an invaluable resource for candidates preparing for the ICAR JRF, SRF, NET, and ARS examinations. Moreover, the books content is relevant to several other national competitive examinations in which Animal Genetics and Breeding is a subject of study.
Animal Genetics and Breeding includes all the aspects of livestock genomics and breeding for better production of farm animals. The general understanding of the subject of animal genetics and breeding is must and till date though there is lot of literature and reviews available, enormous effort is required to arrive at correct conclusions. So this way, I have tried to put my level best to put the information in the book related every aspect of competitive examination of animal genetics and breeding. This book has been prepared on the persistent demand of the students who to require themselves to adopt animal genetics and breeding as a professional carrier. The book provides an outline of various aspects of the science of Animal Genetics and Breeding in object question-answer form. The objective questions have been designed so as to expose the student to all the important competitive examination of Animal Genetics and Breeding. The book would have useful to students’ preparation for various competitive examinations conducted by Indian Council of Agricultural Research (JRF), Agricultural Scientific Recruitment Board (ARS/NET), National Academy of Agricultural Research Management (SRF), Indian Agricultural Research Institute (Ph. D entrance), University Grant Commission, State Agricultural Universities (Pre-PG, Ph. D. entrance), Union Public Service Commission, other agencies and also useful to teachers to keep them abreast with recent developments in animal genetics and breeding and guide their students to a better future.
