One thing to note is that the seed was LIKELY produced from a self-pollination....probably a 'nanner that did it.....the offspring from such a self-produced seed, MAY be that its trait for throwing 'nanners will be magnified....Or, it might not be. On the good side, that plant is almost assuredly going to be a female....for the most part.
EDIT: And yes to what Thundercat said, too!
