Cytogenetics Of Aneuploids

Cytogenetics of Aneuploids deals with the cytogenetic aspects of aneuploidy in plants, emphasizing the trisomics, monosomics, and nullisomics and cytogenetics of substitution lines as well as alien additions and substitutions. An account of aneuploidy in animals and man is also given. This volume is organized into 12 chapters and begins with an overview of terminology and chromosomal formulas, along with a brief history of the cytogenetics of aneuploids as a field of enquiry. The next chapters review the entire literature on trisomics, their sources, cytology, transmission rates, genetics, morphology, anatomy, physiology, and biochemistry. The discussion then shifts to monosomics and nullisomics, including their sources and cytology as well as breeding behavior, morphology, and genetic studies. Other uses of monosomics and nullisomics are considered. The following chapters deal with intervarietal substitutions and alien additions and substitutions, emphasizing different methods of producing substitution lines and their utility in genetic analysis and practical plant breeding programs. The book concludes by describing special features of aneuploidy in animals and highlighting specific cases of aneuploidy in the animal kingdom. This book will be of interest to plant breeders and geneticists.
