2200008 - Equine Genetics
Course Description
The prospect: a horse’s genes determine its potential; from Grand Prix jumper to reining champion, from the perfect child’s pony to the Kentucky Derby winner. In the study of equine genetics, we examine how each horse is a product of its genes. In this course we will examine how the genetics of a horse influence its potential to perform, render it susceptible to disease or unsoundness or curse it with a genetic disorder. This course will take you from simple Mendelian inheritance and medical genetics through the polygenic determination of coat colour and into the quantitative traits such as performance determined by the interaction of multiple genes and the environment. The course will also examine the significance of pedigrees, methods of parentage testing and how breeds are genetically distinct.
Learning Outcomes
The goal of this course is to enable you to understand important concepts of equine genetics and how they relate to the selection and breeding of horses.
By the end of the course you should 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”.

In this course you will explore the following topics:
- The Basis of Genetics: Mitosis & Meiosis; Genes (Introduction)
