Single gene, double gene, triple gene, etc...

...these are fine and wonderful, but what happens when we get far enough along that 'quad', 'quint' and 'sext' gene morphs become hard to identify?

I guess my point is this; will there come a time where its anyones guess, or that we can only partially identify an animal, but there will be open debate on certain animals making them a wrench in the gears of this hobby/business?

Just a thought.

PS - I hope I got these correct - 'quad', 'quint' and 'sext'
