Not necessarily. Hermie issues are often environmental, which would have no effect on progeny. I've had really good luck with "hermie" seeds, and have produced great plants with no real issues. All cannabis will hermie under the right conditions. I will sometimes let a plant run until it produces seeds. One that would normally finish in 8-9 weeks will often start producing seed if you go much beyond that. The most important thing is to keep an eye on your plants. A lot of times they will produce pollen sacks on the lowers first.
Yeah most of the hermie issues seem to be some stress in flowering; light leaks, heat stress, whatever. And all the advice is to throw them seeds away because they're hermie seeds, but if it's just a hermie gene and not a hermie+% increase because it hermied, then just don't stress the plants from said pollen/seeds and you're golden?
I saved my favourite till last and thought I might reveg, but shes been through 3 days of trimming her sisters, lights on/lights off every other hour, chopped her main colas, etc. She is still pulling through. If she doesnt hermie soon, I might just let her go as you said and see if I get some pollen/seeds
