    Df(2L)TW119/Df(2L)TW201 flies show male sterility, deafness and reduced ocelli. Mature sperm are formed in the males, but are amotile. The two cyst cells surrounding the mature 64-unit sperm bundle fail to be degraded and the spermatids that constitute the bundle are not individualised.

    Most Df(2L)TW3/Df(2L)TW201 embryos have homeotic defects in the abdomen, often showing partial transformation of the first abdominal segment to the second abdominal segment. Segment polarity defects and a reduced cephalopharyngeal skeleton are also often seen. Df(2L)TW3/Df(2L)TW201 ; Scm1/+ embryos have severe head defects including almost complete loss of the cephalopharyngeal skeleton, show partial transformation of the 1st abdominal segment to a more posterior segment, and show transformation of the 6th and 7th abdominal segments towards the 8th abdominal segment.
