Breeders i need your help

Given the similarities of the collection though, what I really want to know is if these originated from the same breeding program in the recent past.. eg: Is it possible that these have recent common ancestors?

Possible yes,how likely im not sure.
My private res og came from local farmers who hold it close
The og elite uses is said to be the original larry og cut ...
Im not sure what chemdawg elite used in the chemdawg x sour og
So everybody says they have the real og cut but all i have sampled is the platinum og and its real deal,xcept this purples up at the end {def not pk}

cut a clone then cross her back herm her out and just pollenate one branch why not have some fems seeds and one branch wont kill your stash

Just sampled the private reserve og and its not what i expected,not bad at all just not what i expected.It was very purple and dense and had a sweet note to it,the ones i have in veg smell more like true og...these had finished in 7 weeks and were very stoney meds,but tasted like a og cross maybe...will have to do more research,brbhbr
