is it alive and growing... sure!
i've never seen my yield drop like that after 4-5 iterations.. you can clone for a decade with no problems if oyu always take a healthy part to regenerate.
if you take a part that has some genetic degredation, those defects will then be passed down.
when it comes to questions wholey dependent on knowledge you don't learn in HS, don't listen to "they" on anything... "they" are the same people who think they can stick their hand out the window and dismiss climate change, lol. what's a doctoer with a decade of education beyond HS and multiple decades of experience on related subjects know that i can't know by sticking my hand out a window? BWHAHAHA
