From that last picture im pretty sure i see balls- looks like a hermie.
Ok in that last pic they look like nanners, but again I could just be seeing precalyax formation. Again give it 12 hours of dark and you will be able to tell for sure. cause even at 27 days it shouldn't be that hard to tell
Derek beat me too it. Lower down the plant i def saw some calyx but there were no pistols protruding. She/he is def showing traits feom both sexs. My bets on a photoperiod too. Although maybe because its a hermie thats why its not preflowering or throwing out pistils
If it has male and felmale parts the male parts will open and release pollen and the plant will self pollinate and produce seeds.
You dont want male plants at all unless you want to breed.
If you have other plants it will pollenate them too.
You also have the danger of pollen staying in your grow tent/room and doing the same for your next grow
