Data for 117 U2af-traF feminized gynanders with eggs from the cross w P{Ub-GFP w+mC}33C; P{U2af50-traF w+mW.hs}2B/+; cand1 
× ♂♂ y w sn/YBs. Gynanders were collected within 1 day of eclosion, individually mated to five Oregon-R wild-type males for 5 days, dissected, and examined for evidence of having mated (motile sperm in reproductive tract). Only gynanders that survived the 5-day egg-laying test were included in the analysis (∼15% did not). Not all gynanders were scored for brain and thoracic ganglion sex. Gynanders mosaic on either side for the particular landmark considered were not included.
