Polytene chromosomes normal.
The eyes of fafBX3/fafFO8 flies are severely malformed if the flies are also carrying one copy of lqfAG. Nearly all facets of lqfbE25 fafBX3/fafBX3 eyes contain one or more ectopic photoreceptors in addition to the normal complement of 8. The fafBX3/fafFO8 phenotype is dominantly enhanced by Chc1, no enhancement if seen with Chc4. The fafBX3/fafFO8 phenotype is dominantly enhanced by shiEM42 or shiEM45. The fafBX3/fafFO8 phenotype is slightly enhanced if the flies are also homozygous for shi1 or shi2. The lqfbE25 fafBX3/fafBX3 mutant phenotype is dominantly enhanced by Chc1 or Chc4. The lqfbE25 fafBX3/fafFO8 mutant phenotype is suppressed by effXS347, eff01462, Pros26rv10e or Pros261.
