Estimated growth rate.

The progeny (1 h layoff) from 30 worms for each genotype were scored after 48 h according to their developmental stage. L3 = Larval stage 3. L4 = Larval stage 4. Both presented as percentage. n = Total number of scored worms. Groups that share the same letter (x) do not statistically differ from each other. Groups with different letters are significantly different from each other (x and y). Fisher's exact test. Adj. p-value threshold < 0.05.
