yes, same genetics, but different node growth depending on younger or older motherplant from which the cutting is taken from.
this node spacing does change from that young vegetative growth of symmetrical node growth, to that asymmetrical node growth as the plant goes older. so, you could see if the clone was taken from a young or older plant.
some growers prefer to take cuttings from the lower growth, while others will take cuttings of the growing 'shoots' (tips) of the plant - probably this is preference, but there's some theory behind when to take cuttings or where to take the cuttings from the plant. in the end, each to their own, whatever works....
