      Homozygous germline clones are viable but yield no eggs.

      (Garcia-Bellido and Robbins, 1983)

      First instar larvae do not grow. Mosaic analysis demonstrates mutant phenotype is non-autonomous. Individuals survive when Dp(1;4)wm65g or Dp(1;3)wm49a is present. Surviving males are phenotypically normal and fertile.

      Shows a maternal-zygotic interaction, demonstrated in males carrying mutant allele from heterozygous mother and variegating allele in the paternally derived Dp(1;4)mg.

      (Robbins, 1983)

      Maternal germline clonal analysis demonstrates cell lethality in homozygous clones.
