The science of genetics and genomics lies at the heart of understanding life — from the molecular code that governs the inheritance of traits to the complex interplay of genes that shape evolution, development, and diversity among living organisms. The present book, “Principles of Genetics and Genomics: Concepts, Mechanisms and Applications,” has been designed to provide postgraduate students with a comprehensive, lucid, and updated understanding of the fundamental principles and modern advances in this fascinating field of biology.
The objective of this book is to bridge the gap between classical genetics and modern genomic science. It begins with the concept of genes and their inheritance patterns, explores recombination and gene interactions, and gradually advances to the regulation of gene expression, gene mapping, and population genetics. Each unit is carefully structured to align with the M.Sc. Zoology syllabus (Paper Code ZOSC-6) and provides clear conceptual explanations supported by illustrations, examples, and recent developments in molecular biology and bioinformatics.
Over the past few decades, the field of genetics has expanded beyond Mendelian principles to encompass powerful molecular tools such as DNA sequencing, genome editing, and bioinformatics analysis. This book integrates these modern perspectives while maintaining the simplicity and clarity necessary for students beginning their journey into genomics. The text emphasizes both theoretical knowledge and practical applications, making it equally valuable for students, researchers, and educators in zoology, biotechnology, and life sciences.
The preparation of this book was inspired by my experience as a teacher and researcher in zoology and environmental sciences. It has been my constant endeavor to make complex genetic concepts accessible and engaging to learners. I owe my sincere gratitude to my colleagues, mentors, and students whose feedback and curiosity have continually motivated me to refine and expand my academic resources. I am also thankful to the management of Bhilai Mahila Mahavidyalaya for providing an encouraging academic environment.
I hope this book serves as a reliable guide for students and scholars seeking to understand the genetic mechanisms that form the blueprint of life and the genomic innovations shaping the future of biological sciences. Constructive suggestions and feedback for the improvement of future editions are most welcome.
