Sativa or Indica Dominant Characteristics - Plant ID?

once interbred it gets jumbled, see process of "meosis" so, at that point hard to say one or the other is specifically indica or not because that's just a matter of coincidence that those traits were correlated with a particular plant in a particular region etc etc.. the lankiness is not the cause of any perceived different in high, for example.. merely correlated due to how it evolved in that population of plants. the 2nd picture is clearly shorter and stockier. Historically that would be the "indica"... but once interbred, you could potentially have very sativa traits that are less susperficial and a short stocky plant that resembles a former "indica" classification despite that fact. These are low-resolution terms that don't always tie to reality of what is occurring. if the descriptiosn say one is short and stocky, that 2nd one is most likely that strain... can't be 100% certain, but it is the best guess.
