Book excerpt: When a bird with a single comb, which may be conveniently symbolized as I, is crossed with a bird with a "V" comb such as is seen in the Polish race, and may be symbolized as oo, the product is a split or Y comb. This Y comb is a new form. As we do not expect new forms to appear in hybridization, the question arises, How is this Y comb to be interpreted? Three interpretations seem possible. According to one, the antagonistic characters (allelomorphs) are I comb and oo comb, and in the product neither is recessive, but both dominant. The result is a case of particulate inheritance-the single comb being inherited anteriorly and the oo comb posteriorly. On this interpretation the result is not at all Mendelian.

This book was released on 2011-05-05 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Genetics and the Behavior of Domestic Animals written by William M. Muir and published by Elsevier Inc. Chapters. This book was released on 2013-04-22 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many behaviors in poultry can be modified by genetic selection. Selection of laying hens for maximum egg production had the unfortunate side effect of increased rates of beak inflicted damage on other birds. Selective breeding has eliminated broodiness and has either increased or decreased other behaviors, such as hysteria, fearfulness, appetite in broilers, social dominance, ability and damage to other birds. Genetic selection can be used to reduce behaviors that cause welfare problems. However, it must be approached with caution to avoid unintended consequences that would be detrimental to welfare. A calm, docile bird that appears behaviorally calm, may take longer for its heart rate to return to normal after it is frightened. The use of group selection instead of single-bird selection can be effectively used to reduce undesirable behaviors such as feather pecking and to maintain high egg production. An entire group of birds is selected instead of selecting individuals.
