Preface After the rediscovery of Gregor Johann Mendel’s laws, modern world witnesses the paradigm shifts in research in the field of Genetics. Genetics played a key role in Plant Breeding to understand and develop modern semi dwarf varieties in rice and wheat that lead to achieve self sufficiency in developing countries in Asia and other parts of the world. Therefore, genetics gains an important place in the field of Agriculture. As agriculture is a back bone of any country to sustain its development. In India, Indian Council of Agricultural Research (ICAR) and Agricultural Universities are playing important role in the field of Agriculture by educating students and conducting research to break yield plateau to achieve second green revolution. Therefore, the present book “Objective Genetics” is prepared by covering objective questions with answers in basics of Genetics. In general perception, it is believed that genetics is a tricky and intricate subject. However, we have simplified the subject with objective questions and it will provide a clear, comprehensive, and balanced introduction to genetics at the college level. The questions are briefly and clearly written in comfortable style. The basic of the book is that, any student claiming knowledge of genetics must understand the basics of genetics. Further, this book can serve as a guide for the students who are interested in preparing competitive examination like ARS, NET, SRF, and IAS Exams. We hope that this book will be highly valuable to students of Under graduate and Post graduate studies in appropriate disciplines in Agricultural Science.
