Throughout the book, emphasis is on eukaryotes. However, much additional background information is supplied putting the cytogenetic concepts into a wider biological framework. All the chapters are well illustrated with examples from a wide range of organisms of both plant and animal origin. Extensive use is made in the text of photographs as well as line drawings. This book is targeted at undergraduate students and researchers who need a general introduction to cytogenetics, providing both an excellent introduction and detailed coverage of all aspects of chromosomes. Comprehensive reading lists of original articles are provided for the more specialist researcher.
