Fig. 6. Testing parental RNAi with Oncopeltus Sex combs reduced (Of'Scr). (A) Hatchling from uninjected mother. Arrow indicates labium. (B) Of'Scr pRNAi hatchling. Arrowhead indicates transformed labium. Arrow indicates normal stylet. For a full description of the Of'Scr phenotype, see Hughes and Kaufman (Hughes and Kaufman, 2000). (C) Time course for Of'Scr pRNAi. X-axis is number of days the clutch was laid after injection of the female. y-axis is percent that each phenotypic category contributed to the total. The RNAi effect peaks around ten days after injection and declines after that.
