Ma taxa onse omwe ali pangozi, kuphatikiza nsomba, ndi amodzi mwa magulu asanu. Kukhala m'magulu kumatsimikizira kuchuluka kwa chiwopsezo ku mtundu winawake. Mulingo wachitetezo ndi njira zobwezeretsera zachilengedwe, zomwe ziyenera kukhudza kukula kwa mitundu yazachilengedwe, zimadalira mphothoyo.
Gawo loyamba limaphatikizapo mitundu ya nsomba zomwe zikuwopsezedwa kuti zitha. Izi ndi zochitika zowopsa kwambiri. Gawo lotsatira limaphatikizapo mitundu yomwe ikutha msanga. Gulu lachitatu ndi mitundu yosawerengeka yomwe ingakhale pachiwopsezo. Wachinayi umaphatikizapo mitundu yophunziridwa bwino. Yotsirizira ikuwonetsa kuti taxa yabwezeretsedwa koma ndiyotetezedwa.
