main thing that needs to be discerned and recognized here which IMO feeds the confusion is the difference between chemically induced feminization, nd Rodelization given prominence mostly by the breeder known as Soma
Rodelization is the practice of allowing a sensi plant to flower to seceanance (sp?) which the survival trait or gene is triggered and miniscule pollen is produced. Since one needs to employ this trait for results it inadvertently encourages the dominance of the survival trait/gene which can lead to undesired premature triggering of the trait/gene.
Chemical induced feminization practices on the other hand does not employ nor encourage the dominance of the survival trait/gene. Rather it supplicates or replaces/blocks copper ions in the ethylene receptors. Without the copper ions presence the receptors cannot function and since they do not function no ethylene is detected so the female chromosome does not get triggered and male flowers/pollen is produced. Remember ethylene is a gaseous hormone so the receptors are the only route for triggering the female flower production. So now one can see that there is no botanical possibility for chemically induced pollen to promote the survival trait/gene so often by the misnomer of the hermie gene to dominance as it is in no way sought nor employed by the breeders.
I hope this sheds some understanding that is clearly needed in this area due to all the misconceptions.
