Re: Re: Epigenome genetics

Yes, I agree.

The 'Matrix' example (if they are actually they same clone) is a good example of something that could be worked on that confounds us and illustrates my point.  It sure is a contributing factor why rebloom hasn't caught on in the general public for that particular reason. Maybe we can fix it as we research and observe further into the problem.  If we could figure out how to artificially demethylate (easily and consistently and safely for plants and humans) the appropriate segments of DNA that might be a route to increasing popularity.
