here I have to agree with you! and I will say even more that in some cases the next generation from the germ sometimes has no germ at all.
For example, I like Polm Gold Outdoor from Spliff Seeds a lot, but about 75% of the plants have germ symptoms (probably that’s why the line was discontinued and is no longer available). In order to preserve my favorite variety (which is no longer available) I crossed it with many of my boys. And I have to tell you that some of the crosses had no signs of hermy at all! out of more than 100 plants that have been grown I have not found a single one with germy symptoms.
At the same time, sometimes, parents who did not have these signs manifest them in future births. For example, none of the Space Monkey plants showed signs of germ. Also, f2 SM had no sign. But when I did bx1 (SM#6 x (SM#6 x SM#3)) two plants out of 10 showed the first week 12/12 flowers near the trunk.
therefore, I agree with you that the use of parents with germ traits will not increase their percentage in generations, but the fact that this gene will be present and can manifest itself in a poor plant is indisputable.
to reduce the percentage of this trait in generations, it is necessary to use not only plants that do not have the trait (because it can be hidden), but plants that have passed testing… previously I used the method of “stressing the plant with light”, this is when the plant is turned on several times at night for the night Pure girls with XX thunderosomes do not show signs of germs, all others are forced to show them. In this way, I got the desired results from the offspring.
just my experience, which does not pretend to be the absolute truth…
