Book Description
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).

Book Description
Hundreds of coat color loci have been cloned and studied in the laboratory mouse, and most aspects of the mouse pigmentary system are conserved in other mammals. However, comparative zoologic studies suggest that some components of mammalian pigmentation are not represented as coat color mutations in laboratory mice. This dissertation aims to advance our molecular understanding of mammalian pigmentation, and strives to identify novel components of the genetic toolkit involved in generating the diverse array of coat color patterns found in nature. In the Syrian hamster, X-linked inheritance of the Sex-linked yellow (Sly) mutation results in irregular patches of black and yellow hair in heterozygous females. Femalespecific variegation of black and yellow coat color is also present in the domestic cat, but curiously absent from other vertebrate species. Using a combination of comparative genomics and linkage mapping, I made key contributions towards defining a candidate interval for the Sly mutation and discovering that the hamster and cat mutations lie in non-homologous regions of the X chromosome. Periodic color patterns on animal skin, such as cheetah spots and zebra stripes, are evident across the mammalian phylogeny, but their molecular basis remains a mystery. Taking advantage of improvements in ultra high-throughput sequencing technologies, I developed a methodology called EDGE, or EcoP15I-tagged Digital Gene Expression, that is well suited for gene expression profiling in non-model organisms. Applying EDGE to black spot and yellow background regions of cheetah skin, I discovered that localized differences in Endothelin-3 expression is likely to be responsible for maintaining black spotting through a pigment-type switching mechanism in hair follicle melanocytes. The use of EDGE and other genomic approaches to generate comparative molecular profiles of mammalian skin patterns is likely to open new avenues of research into mammalian pigment patterning and initiate a molecular renaissance for a set of questions that has mostly resided in the area of theoretical biology for the past few decades.
