      Rescues

      if+t39 rescues if3

      (Brown, 1994)

      if+t39 rescues ifB4

      (Brown, 1994)

      if+t39 rescues ifk27e

      (Brown, 1994)
      Partially rescues

      if+t39 partially rescues ifB6

      (Brown, 1994)
      Comments

      Completely rescues ifB4, if3 and ifk27e. Rescues ifB6 to viability though males are sterile, presumably due to the effect of the X to autosome translocation.
