  • Crosses between E(z)Trm/TM3 females and Oregon-R males were transferred from control (nipagin-containing) media to the same media supplemented with Na-butyrate at 0.01 m or 0.05 m concentration. After the flies were fed butyrate-containing media for 6–7 days, they were transferred into bottles containing control media and allowed to lay eggs for 3 days, and offspring hatching from these transfers were analyzed.
