Polytene chromosomes normal.
1.5kb deletion towards the 3' end of the gene which may affect the 3' portion of the H protein.
tormogen cell | ectopic (with HP8)
trichogen cell (with HP8)
Strong phenotype.
H99/HP8 has trichogen cell phenotype, suppressible by Scer\GAL4sca-537.4/numbUAS.cWa
H99/HP8 has tormogen cell | ectopic phenotype, suppressible by Scer\GAL4sca-537.4/numbUAS.cWa
the addition of numbScer\UAS.cWa driven by Scer\GAL4sca-537.4 to H99/HP8 flies rescues the double socket phenotype seen in the external sensory organs in these flies.
Phenotypic series of H alleles, progressing from strongest (amorphic) to weakest mutant phenotype: HB79 = H81 >> H1 = H99 > Hbob > H94a > H88d > HB8 > H2 >= H3 > HA120.
