Flagellar heterogeneity is achieved during the course of at least three cell cycles. Prior to cell division, cells produce two new long, hairy flagella while the parental long flagellum is transformed into a new short, smooth flagellum. The parental short flagellum remains a short flagellum for this and subsequent cell division cycles. Although flagellar transformation requires only two cell cycles, developmental differences exist between daughter cells and the maturation of a flagellum/basal body requires at least three cycles.
