@NaturalTherapy I have grown lots of femminized seeds that didnt show any kind of intersex, but also some that did, the same can be said about regular seeds, again its down to selection of parents.
I think we also need to distinguise between the different kinds of "female" seeds, you have your S1, in the perfect world someone would grow out a million well bred seeds and select the best plants, make S1 with them, test them and only sell the ones with no intersex traits, but as the market is today that is not possible, what we have is millions if different seeds obtained from all kinds of sources are sown and the best of these are saved as clones, then we have all the poor souls like me that dont have access to these wonderfull clones, our option is the S1´s, it might not be the best option, but I have rarely grown a pack of S1´s where I didnt fint atleast one plant worth keeping as a mother, and that is the only reason I grow them, to find that plant to clone.
Then there is you elite clone x elite clone, like ImSoGangstaKush x Very sour DieselDawg, again in the perfect world you would have millions of ImSoGangstaKush and DieselDawgs to select your parents from, but as it is now, if you think the combination of those 2 parents sounds great, your might run the risk of having some plants intersex, but again you select a clone that dont intersex and keep that.
And finaly you have what a few breeders have worked on, properly bred and tested female seeds, not just some dispensary bought clone sprayed with STS and crossed to another dispensary bought clone, but these are just as hard to make as regular bred good quality seeds, so not that many of them yet.
There is also a big difference between a few nanners later in flower and a full blown hermafrodite, the first is not uncommon to find in most strains (some never develop enough to open) and full blown hermafrodites are very rare even in feminized seeds, S1´s too, unless they are very poorly bred
