30 L4 mat-3(or180) hermaphrodites fed with HT115 bacteria expressing dsRNA of indicated genes were shifted to 24°C for 24 h, fixed with methanol and acetone, and then stained with 100 ng/ml DAPI. The numbers of worms that lay only embryos in meiotic division (one cell) and those that lay embryos that had entered mitosis (more than one cell) are shown.
