"I have yet to see any of these genetic defects have any significant effect on the actual end user, the commercial cattle producer."
You might want to get out more or learn more of the details of the defects before you reach a firm opinion. Some of the most recent defect(s) included early embryonic death so that you and others never saw the problem but had late calving animals. But I know a number who had to scrap the bull, lost calves, culled all heifers as potential replacements, ... Mere late calving = lost income. And I do not believe that 036 got clear sailing in the USA. The genetic tests are probably more reliable than a 30 daughter test of the old way if that is the reference.
