Basic Genetics for Dog Breeders


In this online class, we’ll cover the ABCs of basic genetic concepts, from alleles and X-linked genes to modes of inheritance, that dog breeders need to understand to create an effective breeding program. Dog lovers Katie Weihbrecht PhD and Trisha Rettig PhD make genetics easy for all of us! We even have some practical exercises for you to practice doing some analysis of breeding combinations. This online class is a follow on to the Using Pedigrees to Breed Better Dogs class so why not take them both?

This online class is included in our Avidog Breeder College Platinum & Platinum Plus membership.

Basic Genetics for Dog Breeders The goal of this is to introduce breeders to the important genetic concepts that underlie (or should underlie) breeding decisions.

  • What is a gene and where do we find them?
  • What are alleles? 
  • What modes of inheritance do dog breeders need to understand, including the basic simple recessive and dominant, but also covering polygenic, sex-linked, and genes with incomplete penetrance and variable expression.
