Days and confused

Hello all,
I have heard that as part of the survival mechanism of weed you can get all female seeds.

I heard that if you take a girl and instead of harvesting her she will grow a bannana like seed pod that contains all FEMALE seeds? this is done about 30 days past the harvest date.
usually about 12 to 13 weeks.
her genetic copy?
A clone from seed?

any Ganja guru help me with this asexual reproduction question on a plant thats usually sexual.?
thanks
