I'm not completely sure how the phylos galaxy works to be honest.
I have the same question as you concerning how you determine if the OG in mangobiche is actually modern OGKush or if its just hashplants that share similar genetic components.
I'm going to PM Sam and ask if he can explain that
According to phylos "Mangobiche Colombia has heritage primarily stemming from Landrace, with a smaller contribution from Skunk, Hemp." "Mangobiche Colombia is genetically distant from these varieties Bubba Kush.."
So a bit of skunk but no relation to kush.
