Author Profile

Dr. Arun Kumar Tomar is M.Sc. (Ag.) in A.H. & Dairying from J.V.College, Baraut, Bagpat (U.P.) and Ph.D. (Animal Breeding) from CCS, HAU, Hisar. He has worked in the capacity of Scientist (AGB) at C.S.W.R.I. Avikanagar (Rajasthan), Senior Scientist and Principal Scientist (AGB) at Project Directorate on Cattle, Meerut (U.P.). Presently working as Head, Division of Animal Genetics & Breeding, Central Sheep & Wool Research Institute, Avikanagar, Rajasthan. <BR> Professor Sukhvir Singh Tomar is well qualified (Ph.D.), retired Principal Scientist (AGB) from N.D.R.I.,Karnal (I.C.A.R.) having 40 years of research and teaching experience, has published about 300 research articles and 3 textbooks on population genetics and animal breeding. He has long experience for about 28 years as Editor of Research Journal and guided a number of M.Sc. and Ph.D. students.

About The Book

The book entitled ‘Genetics of Livestock Population’ has been divided in 3 parts comprising 27 chapters. The first part of 13 chapters has been devoted to the genetic structure of population in equilibrium state for different genetic systems and the changes occurred under the influence of evolutionary forces, population size and mating systems for qualitative characters. The second part comprises 10 chapters covering the partitioning of phenotypic value, variance and covariance of quantitative characters in to different components attributed to additive and non-additive genetic effects. The last part of 4 chapters of the book deal with the biometrical techniques viz. univariate, bivariate and multivariate analysis and path analysis. <BR> Hope this book will be of immense use to the post graduate students, teachers and those appearing in different All India Competitive Examinations like NET, SRF, and ARS conducted by ASRB (ICAR) as well as by UGC and UPSC. The subject matter has been presented in single volume in a more meaningful and desired manner and simple language with numerical examples.
