Would this be so for plants?  Reptiles (I think) don't have a "sex" 
chromosome (gestational temp often determines sex), birds have XZ and 
XX (and if I remember correctly the males are the XX).  Only mammals 
consistently are XX and XY (and even there they've recently found a 
genus of S. American mice that has XX females and XY Males and 
Females (and the XY Females appear to be "super moms").

I'm just saying I'm not sure how it "works" for plants - I honestly 
don't know, but it may not be a "no male's produced" situation.
