Polytene chromosomes normal.
No P element associated with H. Very complex restriction site polymorphisms affecting fragments of H and downstream regions.
lethal | recessive
visible | dominant
Weak phenotype based on pupal survival. HA120/+ has shortened and interrupted wing veins.
Phenotypic series of H alleles, progressing from strongest (amorphic) to weakest mutant phenotype: HB79 = H81 >> H1 = H99 > Hbob > H94a > H88d > HB8 > H2 >= H3 > HA120.
