Homozygous germline clones are lethal and yield no eggs.
First instar larvae do not grow, those that survive to second instar grow slowly to attain full size before death. Mosaic analysis demonstrates mutant phenotype is autonomous. Individuals survive when Dp(1;4)wm65g, Dp(1;3)wm49a or Dp(1;3)N264-58 is present. Surviving males have rough eyes and are fertile.
Lethality acts in the L1 or L2 larval stages. L2 larvae of variable size.
Judd, 3 May 1963.
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.
Maternal germline clonal analysis demonstrates cell lethality in homozygous clones.
