Part 2. Transmission of Genes from Parents to Offspring

This is the second part of the 5-part course Genetics for Breeders and Vets.

In this part, you will learn about

  • Formation of gametes and fertilisation. How do genes actually get passed from parent to offspring? Why are no two individuals ever born exactly the same? Find out how paternal and maternal chromosomes can exchange parts and how certain genes are always inherited together.
  • The common genome of relatives. Why are relatives more similar to each other than to other individuals in the population? We learn what a genetic relationship is. We will learn why the dam influences the characteristics of her offspring more than the sire.
  • Mitochondrial DNA. Learn why mitochondrial DNA is passed from only dam to offspring. We will also look at a few genetic mutations in the mitochondrial DNA.

Content of the course

This second part of the course consists of lessons, quizzes and a glossary. In addition, each lesson has a discussion section where you can ask questions about the lesson topics.

Your instructor Katariina Mäki, PhD (Animal Breeding), will be present during the course. She will help you if you have any problems and will also answer questions on the course platform.

Four lessons

Each lesson contains a lecture video and the same content in text form.

All the points made in the lecture videos can be found in the text of each lesson. So you don’t have to search for a particular point in the video if you want to go back and check something.

Learning quizzes

Short learning quizzes after each lesson.


The breeding and genetics terms taught in the course are collected in a glossary, where you can always check what a term means.

Possibility to ask questions

A question and comment section after each lesson – you can ask all those questions that have been bothering you for years. Remember, there are no stupid questions!

Course certificate

You can save and share the certificate on social media or print it out.
