There is some confusion on the issue, allow me to clarify:
To answer your original question, growing seeds that you took from that hermaphrodite will result in hermie offspring. The pollin came from and pollinated the same plant. It's a genetic defect that you just bred back into the mother...a stressed mother. So you most certainly can bet most if not all of those seeds will be herms.
The correct way to make a feminized seed involves TWO healthy females. You induce hermaphordism on one of the females using a foliar feed of silver nitrate, the stuff they use to 'make rain'. You collect that pollin and use it on the OTHER healthy, stress free, female. When you feminize a good F1 hybrid, those seeds will be less likely (not 100%) to turn herm.
Don't even waste your time with those sprouts, if you do, you're going to wish you've listened to me, it's messy when the whole crop herms on you, very depressing.
