no, dragongack. dr. donald blake was very much thor. odin created the body of blake to imprison thor to teach thor humility. so the dna is still the same, it's just the magic of odin that made him a cripple. and stark & richards cloned thor from a stran of thor's hair... from when he was thor, so the dna was there.
I'm kinda puzzled...if they cloned THOR and he's a God like Mystical being who transformed from a whimpy crippled Doctor wouldn't they end up with a clone of the Doctor not THOR?
