And no, I don't expect any fireworks. I'm here to learn. If I'm wrong I want to know it.
John, I think what you don't quite grasp is that in linebreeding the focus isn't so much about traits governed by simple Mendellian inheritance as it is about traits governed by quantitative inheritance. What you try and do in linebreeding is as much stacking the good genes as it is about eliminating the bad. In quantitative inheritance dominant and recessive often plays no role.
