You are confusing hermaphrodism (degraded genetics) with stressing a lady of sound genetics, to collect the resultant pollen. Technically...every single cannabis plant is a 'recessive' hermaphrodite.

Let me repeat...Every strain of cannabis I've ever grown has the ability to to hermie, and I have never found one I can't hermie. (autoflower strains excluded, as I don't work with those every day) It's a self-preservation skill cannabis learned nearly 10,000 years ago without human intervention.
Likely cannabis had this ability before being spread around the globe, because it's inherant with cannabis seeds now native to all continents but Antarctica.
97.3% (a made-up number to make the response look good) of so-called 'hermaphrodite' nanners are gardener-induced, through stresses of their own making. Most of the time it has nothing to do with a strains' genetics being degraded.

Granted, with all these 'backyard breeders' using metals, chemicals, hormones and steroids to fem their seeds...the chances of creating a genetic hermie increases. This is one of the reasons that I will never purchase femmed seeds. (Well, that and the fact that I fem my own without genetic malformaton)
