Df(3R)A177der25/Df(3R)A177der22 embryos show normal development of the hindgut, midgut and Malpighian tubule primordia. The second midgut constriction and muscle pattern form normally. The cuticle pattern is normal, except for defects posterior to the eighth abdominal segment. Df(3R)A177der20/Df(3R)A177der22 animals die during embryogenesis.
