Depends.
Is the strain a true IBL, or is it an F1 hybrid?
If it is an inbred line, your seeds will be as good or so near to the seeds you bought that it is basically the same plant. The seedbank will obviously be using very good individuals to make their crosses.
If it is an F1 hybrid, in your 'F2' generation you will see phenotypic variation that will be more noticeable based upon how similar in traits the 2 parents were.
