<i>lip-1(lf)</i> and <i>let-60(gf)</i> mutants do not show radiation sensitivity.

L4 larval stage worms were treated with either 0 or 30 Gy of irradiation and allowed to recover for 24 hours. Worms were then transferred to fresh plates in triplicate and allowed to lay eggs for 24 hours. The number of eggs laid was counted immediately after removing the adult worms and the number remaining was counted 24 hours later (which is sufficient time for L1 larvae to hatch). aThe number of eggs laid is the average number per hour (± SEM). bSmall eggs were defined as those that were round (instead of oval) and half the size or smaller than normal eggs. cOocytes were identified by their brown colour and flattened appearance.
