Built precisely on the 21-unit ICAR Sixth Deans' Committee syllabus, this book transforms the vast and concept-rich field of Genetics into concise, high-yield, and examination-focused learning material for undergraduate students of Agriculture and allied sciences. The text presents fundamental principles of classical, molecular, and quantitative genetics in a simple, systematic, and student-friendly manner while retaining scientific rigor and conceptual clarity.

Each chapter begins with crisp definitions, learning objectives, and key concepts, followed by classic experiments and contributions of model organisms that shaped modern genetics. Complex topics are simplified through diagram-first explanations, flowcharts, and concept maps, enabling students to visualize genetic processes and retain information more effectively.

The book provides worked examples and solved numericals on probability, Mendelian ratios, test crosses, pedigree analysis, and Chi-square (χ²) testing. Step-by-step protocols explain important techniques such as genetic mapping, mutation induction, doubled haploid production, and cytogenetic methods. Compare-and-contrast tables are extensively used to distinguish chromosome architecture, special chromosomes, mitotic and meiotic divisions, linkage and recombination, qualitative and quantitative inheritance, and mechanisms of gene regulation.

Special emphasis has been given to examination preparation through rapid revision tools, memory aids, summary tables, and question banks that closely reflect university and competitive examination patterns.

Dr. Archana Rani is currently serving as a Senior Research Fellow in the Department of Plant Breeding and Genetics at Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur, Madhya Pradesh. She holds both her Master’s and Doctoral degrees in Genetics from Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar, where she was awarded university fellowships for academic excellence throughout her postgraduate studies.

With nearly a decade of professional experience in agricultural research and academics, Dr. Rani has significantly contributed to several key research projects, including a Japan –funded JICA project on the Evaluation of promising soybean genotypes under excessive soil moisture conditions and the ICAR-funded CRP on Hybrid Technology in Wheat. Her teaching and research engagements have also extended to U.P. College (affiliated with LNM University, Darbhanga) and her alma mater in Pusa, Bihar.

A major milestone in her career is her association with the development of the wheat variety MP 3535. Her scholarly contributions are substantial, with over 30 research papers, 19 book chapters, and 27 extension articles published in reputed platforms. She is also the author of the academic book Agricultural Biotechnology – Concept and Practices, which reflects her expertise in the field. In recognition of her scientific contributions, Dr. Rani was honored with the Young Scientist Award at an international symposium held at Sido Kanhu Murmu University, Dumka, Jharkhand. Her active participation in 17 national and international seminars, symposia, and training programs further underscores her commitment to continuous learning and knowledge dissemination in the agricultural sciences.

Dr. Stuti Sharma, Assistant Professor at the College of Agriculture, JNKVV, Jabalpur, holds  M.Sc. (Ag.), ARS NET, and Ph.D. in Plant Breeding & Genetics. With eleven years of experience in research, teaching, and extension under AICRP on Soybean, she has significantly contributed as Co-Breeder of six Soybean Mega Varieties—JS 20-69, JS 20-98, JS 20-94, JS 20-116, JS 23-03 and JS 23-09 along with two Urd bean verities TJU 130 and TJU 339 . Currently, she serves as In-charge of DUS, PPV & FRA, AICRP on Rabi Pulses, and also as the Liaison Officer of the university. She has been recognized with a National-level silver medal in debate during her undergraduate studies and has received six national awards in research. Dr. Sharma possesses expertise in statistical and biometrical data analysis, traditional breeding for abiotic stress tolerance, yield trial management, breeding generation handling, and scientific writing. She has published 55 research papers, authored 4 books, and presented 40 abstracts at national and international conferences
