I don't know which if either carries more genetic material than the other but I've used both feminized and regular seeds for making seeds. I've pollinated feminized plants with both regular pollen from males and reversed pollen from feminized females. I've pollinated regular females with feminized and regular pollen. I've never had any hermies from any of the combinations of regular or feminized when making seeds.
Now I know people like to blame the genetics for hermies but I think that excuse is used far too often. I fully believe that much of what people blame on genetics is actually caused by the grower. Stress can cause hermies and stress can be caused by a number of factors. Overfeeding can cause stress and the way many people are dumping a dozen bottles of this and that on their plants I believe they are stressing them by overfeeding. There is also the fact that many of these nutrient companies are putting substances in their products that are not listed on the label including PGR's which can definitely cause hermies.
I'm not saying that hermie traits can't be passed down through genetics, I'm saying that genetics are an overused excuse when the cause is actually due to the grower and something they have done. As far as hermies being passed on through genetics, landrace Thai strains are knows for hermies and they have been used to create a good amount of the current modern strains.
Another common scapegoat for hermies is that the grow light was left on for a few hours longer than normal. I'm not going to link to a particular post but there have been numerous posts where a few hours of extra light or a couple pinholes in a tent were blamed. The plants in those posts are typically overfed, heat stressed, nasty looking plants which is more than likely the cause of any hermies. Not genetics and can't be blamed on the breeder.
I have no scientific proof to back up what is just my opinion but in my decades of growing I've had fewer plants hermie than some of the newer growers that have only a couple grows. I'm convinced that stress from overfeeding and dumping too much crap on plants is stressing the plants out resulting in the growing instances of people having hermies.
