People do not possibly comprehend the accuracy required for genetics tests to have any validity, of which even current companies aren't the best at. By using a company like Amway, all that you're going to get is very rough probabilities, exactly the opposite of what consumers want, but what they'll be left with, since they naturally cut corners and need to do a CYA job, leaving that as the net result.
The only hope I can come of with this nonsense is that people begin realizing the NEED for accuracy on scales beyond you can imagine as a result of the useless of genetics tests when you don't do them right.
Note: I've already done these tests (NOT Amway, of course), which is why I know what I'm talking about here.
