The book is basically intended to accompany cytogenetics students of Genetics and Plant Breeding. The present book with the help of diagrams and explanations it has been attempted that even a beginner could grasp the core elements of the subject. The book has been strictly organized on the basis of course curriculum of being taught in Universities. All the topics covered in the book have been ordered in a crisp and comprehensible manner avoiding complexities of a traditional textbook since it is a simply a guide book to supplement but not supplant the main texts.
