Fig. 2. Quantitation of the number of cell corpses during embryogenesis. (A) Wild-type N2. (B) cdl-1(e2510). (C) cdl-1(e2501). (D) cdl-1(w37). (E) mnDf90/cdl-1(e2510). The y axis represents the average number of cell corpses visible in embryos of each genotype at each stage. Stages are defined as follows: 220
310 minutes (I), 320
410 minutes (II), 420
510 minutes (III), 520
610 minutes (IV), 620
710 minutes (V), and 720
810 minutes (VI) after first cleavage. Error bars indicate s.d. Numbers of embryos examined were (A) 17, (B) 23, (C) 11, (D) 8 and (E) 32, respectively. Asterisks (*) indicate that the difference from the wild type at the same stage is significant (P<0.01).
