I have been told that bell peppers are male and female .

Question

On the bottom side of bell peppers some have 3 lumps and some have 4 lumps. Does this indicate whether they are male or female or just a wive’s tale ?

Answer 1

All bell peppers have both male and female parts. The central portion of the flower with a "ball" on it is the female portion, whereas the yellow pollen bearing anthers that surround the female portion are male organs.
