An Introduction to Form and Feathering of the Domestic Fowl

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.
