In this episode of Bred to Perfection, we are talking about what constitutes contamination and the effects it can have on your strain and the future of their breed. Whether you are creating a strain, or working to improve an established strain, the introduction of the wrong blood can set you back for years. It could even destroy the strain forever. Join us as we talk about what this means and how to prevent this from happening to you and your strain.  We also talk about the functions and benefits of using sub-lines. I know you will find this interesting as well.
