Description

Equine Color Genetics, Fourth Edition presents a detailed examination of the color variation in horses and donkeys and the genetic mechanisms that produce color variations.

  • Thoroughly covers the basic colors in horses, including bay, chestnut, black, and brown
  • Details the genetic basis of the colors built from the basic coat color, including dilutions and white patterning
  • Provides an explanation of genetic mechanisms that determine coat color
  • Presents a thorough revision and update, including new advances in molecular genetics, biochemistry, molecular mechanisms, genetic loci, coat colors before domestication, and more
  • Offers a new introduction describing the principles of genetics and genomics research to help outline how knowledge is discovered and to assist the reader in understanding concepts covered in the book
