In case of seedless varieties they do not create clones they spread “through cuttings”.

In nature there are plants that self-fertilise and create clones of themselves! They keep the option of cross pollination because plants don’t move and they need an individual able to do said fertilisation.

By creating clones you move in time… and space, so that cross pollination can happen.

*Except if you are peas!! In which case you are perfect the way that you are and you don’t need anybody else! Lol
