Course Description

Learn and understand important concepts of equine genetics, how they relate to the selection and breeding of horses, and how each horse is a product of its genes. Examine how the genetics of a horse influence its potential to perform, or render it susceptible to disease, unsoundness, or genetic disorder.

You will be guided from Mendelian inheritance and medical genetics to the polygenic determination of coat colour. Study the quantitative traits determined by the interaction of multiple genes and the environment. The significance of pedigrees, methods of parentage testing, and how breeds are genetically distinct will also be covered.

Learning Outcomes

Upon successful completion of this course, you will be able to:

  • Explain the fundamentals of Mendelian genetics and how they apply to the expression of genetic disorders and determining coat colour
  • Explain the concept of heritability for quantitative traits such as conformation and performance, how it is applied in a breeding program, and what it means in terms of the relative contributions of genetics and the environment
  • Describe DNA testing and parentage verification of horses
  • Investigate and discuss the development of breeds and how selection, reproductive isolation, and bottlenecks contribute to the genetic identity of a breed
  • Compare and contrast the genetic connections and distinctions between the various species that are all considered to be members of the genus “Equus”
