" the brand new discovery of RNAi (basicly a RNA security function that removes suspicious DNA copies and any DNA copy that resembles the suspicious DNA) we can turn off genes at will."

I must add that RNAi will also remove the original DNA code that the "suspicious code resembles".

Ahh there's the rub. Over time (seven generations) the offspring will begin to show the effects of the experimental gene removal in ever more bizarre manifestations.

This is getting spooky ;)
