@Livinginawe might be pertaining to the phenomenon in which there's no meiosis involved. Mangosteen is one of them which bears seeds that are supposedly not genetically different from the tree they came from. The ovules seem to be self-fertile, like 'immaculate conception' among komodo dragon lizards, except that with mangosteens, there aren't any rearranging of chromosomal gene pairs.
and if actually self-pollinated, the pollen apparently weren't capable of meiosis either. All of them--clones and drones.
