I don't have proof that I can show you. But it's common sense, not being cheeky. I will explain, any traits that a plant, or animal for that matter, has will be passed down to future generations by breeding.
So if for example, my snake, is an evil bastard and it has young, they are more than likely to have the same traits.
Same with plants, if they are stretchers, they will most likely breed stretchers if it is in the genetics and not just bad light.
So in my opinion, and it is only my opinion, if the plant throws out male flowers on a female plant, the seeds produced will also want to do the same.
I have read that if this happens, you can breed it out by selective breeding over about 5-8 generations. Can't remember where I read it, I read so much that I can't remember where all the information comes from.
I absorb information like a sponge lol
There is so much hermi plants going about from street dealers that have seeds in them and when people think they are ok to grow them, they happen to get hermi plants from them.
I am not a scientist so I cannot back my claims up with fact and have not tested it either.
Maybe you can test it so you know for yourself as thats always the best method of finding things out
