Percentage of pro-Sftpc− cells per mutant clone at 4 days (H), 1 week (I), and 4 weeks (J) post-induction. Color and size of dots are scaled according to clone density. Dashed line, boundary between slower- and faster-cycling clones. For (D)–(J), n≥ 3 mice per time point (total numbers of clones and mice analyzed are given in Table S1).
