I don’t think YY viable since sterile right? So maybe XY is 66% and XX 33%. Only female have viable mitochondria and male male has no good mitochondria so incomplete chromosome chromosome is messed up or mutation around centromere or do plants not have centromere???
It's a mystery for sure! But, I'm speculating that, since a male has both an "x" and a "y" - it can produce all those combinations in its selfed seeds, just like it does in combination with a true "xx" female.
