That was an interesting read, thanks for the link.
It doesn't help your argument. I said pretty much what they did, in simpler terms.
If a plant has XX or XXXX chromosomes, it is not a hermaphrodite. It can be stressed into producing male flowers, but the resulting seeds, if crossed with a plant that was XXXX, will be feminized. Those plants would have XXXX chromosomes.
If you get genetics that are XXXY you could of course get a hermaphrodite. I did not say anything counter to that.
I agree with the summary where they say you can't reject epigamic or genetic thought when talking about sex determination. They both influence sex.
at the same time, if you stress an XXXX, it can not produce offspring that have a Y chromosome unless the plant it is crossed with has a Y in there somewhere.
Some varieties are more likely to have hermaphrodites.
If you take a variety that is not likely to have hermaphrodites, how does making feminized seeds from that make it more likely to produce hermaphrodites?
It doesn't make any sense, especially after reading that article.
By removing the Y chromosomes it would seem like you would be less likely to have non-stress induced hermaphrodites than with regular seeds.
