Book Description
In this introduction to the genetics of form and feathering of the domestic fowl you will fi nd a straightforward method that allows anyone, beginner or advanced hobbyist, to understand how the major genes of form and feathering come together to create the silhouette that is the hallmark of each breed. Beginning with a discussion of the skeleton genes, then moving to muscling genes, feathering genes and fi nally to comb genes, an understanding of the layers that make the silhouette is revealed. From this system of understanding how the silhouette is formed, one can then understand what really makes one breed unique from another. All of the genes presented herein are found in the commonly seen exhibition breeds and many hobbyists will be familiar with these breeds, but may be less familiar with the genetic factors involved. This volume is a wonderful tool for learning the basis of how the breeds are made, how their respective forms are derived from separate genes of form and feathering, and how those genes all come together to make the one visual impression that we consider a breed. There is in fact no one single gene which makes the form of any given breed. Many genes are required to derive each type and the combination of those many genes creates the silhouette. As you will see from the many silhouette illustrations in this book, once you know a breed, it is instantly recognizable from its silhouette alone. In addition to the discussion of the genes, there is a discussion of basic genetic concepts and of the complex and often confusing method of quantitative selection that is very applicable to many of the genes described herein. This book presents a very clear system for learning about the genetics of form and feathering in the domestic fowl and is written to be understood by the young and beginners alike.

Book Description
This is a lengthy, but exciting novel of how a promising young boy becomes molded into a horrific individual. It explains about the person's life in such detail, that emotions literally explode into a wavering array of uninterruptible events. Leading to endless scenes of inhumane atrocities. Feeding on this individual's frail and developing psyche. ALLEN SHAW: "The chainsaw man," became what all people would come to fear the most. Something out of our darkest dreams. Driven solely by an incurable rage inflicted on him by a mixture of influences. Taking the reader directly into the mind of this gruesome monster of a man who carries a chainsaw. Dwelling in the famed "BIG THICKET" or Texas. This novel will take one literally back to a time in the 1960's 1970's; It's drastically differed ways of thinking, and ways of life. Where the great American landscapes were still fiercely ever in tact. It's values, and ways of conversing with all that is inside. It's ways of being. A literally terrifying novel where one is chased forever in this thick tangle of jungle-like Texas land. A blood encrusted warrior who does the unspeakable. It will undoubtedly frighten, but it will equally reveal a heartfelt pain that is very real among most of us. "The need to be loved and accepted." This torture survivor remembers a different place: a different time. It is told now in the long gone genré of a good old fashioned horror/slash thriller that WE of the 70's know and will fondly recall. I take the reader by the hand and lead him into "my" world. Where the realities that men do onto unsuspecting others. The horrific impact following. The literal mental state that thrives ever so fluently in the collective unconscious of modern man. Never forget that he is stalking you! "Don't go in the woods alone . . . The "CHAIN SAW MAN" is coming!!" For the chain saw man will forever live in infamy . . . In the back woods of us all.

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).
