phenotype: Eyes rough. Bristles irregularly reduced in size and number. Abdominal sclerites often smaller. Developmental study by Lees and Waddington [1942, Proc. Roy. Soc. (London), Ser. B 131: 87-100] shows that effect on bristles results from general slowing of bristle growth. Female entirely sterile, with underdeveloped ovaries. At l9oC, bristles nearly normal and eyes nearly wild type. RK2 at 25oC and above.
cytology: In salivary chromosome region between 59E2 and 60B10 based on its being to the right of In(2R)bwVDe1 = In(2R)41B2-C1;59E2-4 and to the left of Df(2R)Px = Df(2R)60B8-10;60D1-2 (Bridges, 1937).
