I did this by accident once..
if you pollinate a feminized (female) plant... you'll get seeds. I ended up with 3 seeds from my accidental pollination event. Out of curiosity, I germinated all three to just see if they were even viable. Sure enough.. they were viable. They actually did quite well actually.. and all three ended
up being female plants.
I'll let you figure out the rest.
You should read up on biology and botany.
peace.
