Iipleyiti zenkcubeko yeeseli zisetyenziswa kwiilabhoratri ukubonelela ngezona meko zilungileyo zokukhuliswa kweeseli. Ipleyiti yenkcubeko yeeseli ibonelela ngeemeko ezifanelekileyo zokukhula kweenkcubeko zeeseli. Zihlala ziselubala ukuvumela uvavanyo olubonakalayo, kwaye izitya zinokuba ngu-V, zisicaba, okanye zingqukuva ezantsi. Bahlala beneziciko zokukhusela iisampulu ezinokuthi zibekwe kumaqula amaninzi ukuze zigcinwe, zilinge, kwaye zihlolwe.
