>>22846077>>22846095It's definitely possible to produce good hybrids, but there are two things to be aware of:
1. One generation of hybrid vigor doesn't imply continued vigor in later generations.
2. What is the _rate_ of good hybrids vs bad hybrids, and is this an acceptable rate you're willing to live with?
Humans are of course not dogs. This was just an example to illustrate a point.
I'm not so much trying to say why mixing should never be done, as I am highlighting the realistic philosophy why it might not be a good idea.
