This book is very useful for the M.V.Sc. & Ph.D. students of Animal Genetics and Breeding discipline as well as Poultry Science discipline studying in veterinary colleges all over India and South East Asian countries. The information available in the book is very much useful for the veterinarians working in private poultry hatcheries all over India. This book deals with Zoological Classification of Birds, Growth of Poultry Industry in India, Poultry Statistics, Introduction to Molecular Biology, Principles of Genetics, Qualitative and Quantitative Traits in Poultry, Inheritance of Quantitative Characters, Sex Determination, Sex Linked, Sex Influenced & Sex Limited Traits, Economic Traits in Poultry, Values and Means, Average Effect, Breeding Values, Variance, Heritability, Repeatability, Correlation, Selection and Mating System and Use of Molecular Markers in Poultry Breeding. This book is useful for veterinary post-graduate students to face National Eligibility Test (NET) conducted by Agricultural Scientists Recruitement Board (ASRB), veterinary graduates who are all pursuing competitive exams conducted by State Public Service Commissions and Biology/ Veterinary graduates preparing for Union Public Service Commission (IAS/IPS) exams.
