Marijuana Grafting

Hello, I was wondering have any of you have ever grafted marijuana? Do you think that by grafting branches from different strains to a plant it would alter its genetics? If any of you have pics of grafted pot plants please post them. Thank You

I heard years ago about grafting them onto alfalfa but I don't know if that was a bunch of crap or not.

I've heard by grafting you just produce a multiple strain plant. Each branch would be its own strain tho. it would not change the genetics.
