If it comes from a herm, it will be feminized seeds, but if it naturally hermed you are passing down a very bad trait - it doesn't mean they all will be herms but definitely increases the risk for no reason.
all fem seeds come from a hermie plant, but they don't naturally pop nanners and sacs. A chemical or other procedure is done to cause the development of male pollen sacs.
Can't tell if anything is pollinated for sure. Could pull off a calyx and dissect it.
Lone "nanners" are not very productive and often have inviable pollen, but if you had a pollen sac, that could pollinate 100s if not 1000s of seeds by itself.
