Then the self sterility is always genetic ? ( I wasn't sure of this point

And then, why can you 'force' the germination of the pollen, mixing the
plant pollen with another one ?

And what would be be the genetic reason ?

But you can hybrid it, no ?

And do you have an idea of wich cp are self-sterile ? Is there a familly or
a gender where all the plants are self-sterile ?
