      CTCFE5.5 homozygotes are pharate lethal. Male genitalia are rotated by 40[o]-90[o] in 100% of cases. Males exhibit A4 tergites with patchy pigmentation. A5 tergites show a few white spots, the A5 sternite is elongated into a banana shape. Eight bristles are found on the sixth sternite, and the seventh tergite is smaller than in wild-type. CTCFE5.5 homozygous females exhibit A7 sternites with up to 11 bristles pointing vertically downwards.
