is it possible for a plant to show both male and female nodes

of cousre i am a newbie on my first soil indoor grow using 400 watt hps light , big bud , white widow , and some good regs seeds , oscilating fan ,ozone generator , black and white reflective film , and pro grow and bloom nutes ...i only vegged for 12 days at 18/6 and now 35 days into grow . started with 31 seeds and after killing off the males , now there are 12 females .
2 of the plants totally look like females except for a couple of balls that are confusing me . my question is can a plant have both characteristics of a male and a female ? also where can i download my pics ?

ok !!!!!!!!! now if the plant only has a couple of balls and the rest of the plant is female .............can the balls be taken off before they open and pollenate the the females ?

yes, but if they are turning this early, chances are you'll be fighting a losing battle.

i kill of all herms. i've experimented with reversal, but i think that the hermie genes will eventually cause the demise of a great project, rant rant rant, and i elliminate them.

It can sort be like cutting toenails they might be slow but they tend to grow back (unless you knock them off ouch).
