The science of genetics has undergone a period of very rapid and significant development in recent years, and the area of poultry genetics has been no exception. This book provides a balanced and up-to-date account of all the major areas of this subject from Mendelian to modern molecular genetics. The book begins by tracing the evolution of Gallus domesticus from its avian ancestors. Subsequent chapters cover important aspects of poultry genetics, including cytogenetics, transmission genetics, gene mapping, sex linkage, lethal genes, genetics of feathering and plumage, and quantitative genetics. In each chapter, a concise explanation of the genetic principles is followed by a full discussion illustrated by key examples. In the latter part of the book, recent advances in gene cloning and sequencing are examined. The impact of these exciting new developments on our understanding of gene structure and organisation, immunogenetics and the evolution of proteins is assessed. Finally, the uses of transgenic techniques and their implications are discussed. This book provides a clear and useful survey of the genetics and evolution of the domestic fowl, which will be of interest to postgraduate students and researchers in the fields of genetics, agriculture and veterinary medicine, as well as to poultry breeders (both commercial and non-commercial).

"Prior to implementation of the Package 118 restoration program in Harpers Ferry National Historical Park, the park's archeological research staff conducted excavations around Park Buildings 5, 7, 16, and 16A. During the summer of 1991, a crew of four people excavated 11 units (typically 5 ft. by 5 ft.) in the backyards and under Park Building 16 where the flooring had been removed. This work gave the archaeologists the opportunity to examine firsthand and to re-evaluate the soil layers and some of the features described in previous reports. Also several additional features were discovered. This new report presents the findings of an interdisciplinary effort covering topics beyond the basic descriptions of soils and artifacts. It provides glimpses into a small piece of the town, crowded with buildings and busy with the everyday activities of families and small businesses such as a bakery/confectionery, saloons, a shoemaker's shop, and a dry goods store. ..."--Management Summary--page xiii.
