Genetic variation is fundamental to the evolution of all species and is what makes us individuals. This course focuses on heritable variation and will give you a taste of the resources you can use to explore genetic variation data.

Feedback and help

Who is this course for?

This course is for anyone who would like an introduction to key concepts in the field of human genetic variation including the types of variants, variant effects and genetic variation studies. An undergraduate knowledge of biology would be an advantage.

This is part I of our course on human genetic variation. In part II of this course we will learn how to explore publicly available genetic variation data.

What will I achieve?

By the end of the course you will be able to:

  • Review sources of genetic variation
  • Describe the possible effects of genetic variation
  • Identify common genetic variation file types and formats
  • Describe types of genetic variation studies

What resources do I need?

There are no specific resources required to complete this course.
