very good info here for sure. on a side note, i've noticed a surprising number of peeps don't follow the genetic lines they work from seed or clone, at least in background.
great example is "White Fire OG" or "WiFi" from OGraskal. was never released as a regular offering, only from fem seed, the crossing of two females. WiFi#43 is, simply put, a selection from 100 fem seeds, run by Jungle Boys.
as such, if you femmed a WiFi clone from the source, those are re-femmed seeds, i believe the correct term is R2 at that point. GMO is another, found in a pack of Mamiko "Chem Cookies", which are again feminized seeds, created from crossing two females.
not saying these lines are weaker in any sense, with selection comes keepers regardless.
