It was the strategic error of Simon when he was forced to reboot his lab (shit happend, i don’t judge that) but have continued to release the “new Chronic” under the same reference. So not as a new strain/new line.
He have losted a lot of his (hard earned and deserved) fame in this operation back in the days.
I think it’s honest to don’t sell a backcross under the reference of a pure inbred line, now i still don’t known about what and who we are talking about lol
The “truebreeding” term doesn’t exist in my native language, and have no technical equivalent too.
But a poly-hybrid can be dominant over a very wide panel of lines, this is not so Manichean in practice. The white widow being the most worldly known example of that imho
