Ka bokhutšoanyane, metaphase ea cellular ke mohato o mahlonoko oa potoloho ea bophelo ba sele, moo li-chromosome li ikamahanyang bohareng ba sele pele li arohana le ho abela liseleng tsa morali. Nakong ea ts'ebetso ena, likarolo tse 'maloa tsa cellular li sebetsa ka kutloano ho etsa bonnete ba hore li-chromosome li ajoa hantle, ho qoba liphoso tse ka bang le liphello tse tebileng tsoelo-peleng e tloaelehileng ea lintho tse phelang.
