In combination with other aberrations

Dp(1;Y)shi+1/Df(1)19 larvae lack the mouth hooks and cirri and the lateral process is shortened. The H-piece and hypostomal sclerites are absent and the antennal sense organ is not usually seen.

NOT in combination with other aberrations

Heterozygosity for this deletion enhances the mutant ovarian phenotype of ovoD2.

Homozygous and hemizygous embryos fail to hatch to the first instar larval stage. CNS is normal but Bolwig photoreceptor cells are defective.

Second break unspecified, but proximal to 14A1.

Distal breakpoint maps between 7.5 and 8.5kb upstream of Myb transcription start site.
