<p style="text-align:justify">The book&nbsp;provides a comprehensive understanding of chromosome biology, chromatin organization, and molecular cytogenetic techniques with special emphasis on their applications in genetics, plant breeding, and agricultural sciences. The book introduces the fundamental concepts of cytogenetics, tracing the historical development of chromosome studies and the contributions of pioneering scientists to modern cytogenetic research.</p> <p style="text-align:justify">The text systematically explains chromosome structure, chromatin organization, specialized chromosomes, and chromosome landmarks, along with detailed discussions on chromosome banding techniques such as Q-banding, G-banding, C-banding, and R-banding. Advanced molecular cytogenetic tools including FISH and GISH are also covered for genome analysis, gene localization, and hybrid identification.</p> <p style="text-align:justify">Special emphasis is given to chromosome number variations, haploidy, polyploidy, aneuploidy, and structural chromosome aberrations, highlighting their significance in evolution, crop improvement, and breeding programs. Designed for students, researchers, and professionals in genetics, biotechnology, and agricultural sciences, this book serves as a valuable resource for understanding modern cytogenetics and genome analysis techniques.</p>
