If that was meant to answer my questions, I'm sorry, I can't see any relevance in the linked blurbs.
Since you haven't gotten an answer ... and this is all how I Understand It and might not be complete enough ... and I'm really fucking High Soooooooooooooo Here it is In A Nut Shell. Passes on Male Genetic Code of that strain or hybrid ... IDK they just grow Balls ... an intersexed gene in a plant can cause a normally Male and Female (dioescious sp?) flowering plant to produce flowers of Both sexes. There are concentrates, hormones and chemicals used to induce this Shim to make a plant reverse and Monsanto has a Gene Slammer ... I would consider them a Modifying of Genes, Alien Science or Witchcraft. Then there's the Environmental Stress applications (let go Looooong in flower ... light poison the dark cycle ... radical pH fluctuations ... completely bizarre feeding etc etc) ...Could someone tell me what the male (Y) chromosome does? How does it make the plant grow male flowers?
What about intersexed genes/modifiers? How do they modify the sex of the plant?
What mechanisms are at work? What are the pathways?
In this light, and with much stronger arguments too imo, could we not go on a rampage about how folks who use M/F programs are fucking everything up, lol? Justa jab -T

ive turned quite a few M/F polen chuckers into Fem polen chuckers,,,,ive done this because i hold a strong argument that folks who select males using maily guesswork would be better using females!!,,,,everyone wants to reintroduce the Y chromozone later as a novelty but that IS COOL!!
imho,,,,,there is mutch less chance of accidently aquiring bad recessives with fem breeding,,,

lol
im allready being passive-agressive towards this issue,,,
