Table 1. rab11-null FSCs have a wildtype or near wildtype half-life.

	% marked germaria at different days ACI (total number of germaria counted)
genotype of marked clones	11	16	24	Half-life
FRT5377, rab11-null	18.1 (204)	14.8 (203)	11.2 (155)	17.2–19.0 days*
FRT5377, rab11+	18.7 (315)	15.7 (191)	12.1 (298)	19.8–21.2 days*

*half-lives were calculated for each of the two intervals 11–16 days and 16–24 days using the equation half-life = elapsed time (days)×log 2/log [initial percentage/end percentage], which assumes that FSC loss occurs randomly, and thus linearly over time.
