Okay, the other thing about mitochindrions that makes it "special" is that it has it's own DNA and that DNA is passed only through maternal lines. I also want to say that it's that that at one time the mitochindrions was an independent cell but through evolution it developed a symboitic relationship with other cells ...but I have to check my facts on that one.
Now, the thing with the DNA only being passed though maternal lines is interesting because it makes me wonder if GL would take it that far or if he decided to make some kind of weird twist like because Anakin only has a mother could he then pass on his midis to his kids where as normal men couldn't?..I don't know..it's a thought though.
