Description

Imprecise excision of the P{PZ} element, deleting Fab-8 boundary and iab-8PRE silencer sequences in the Abd-B downstream regulatory sequences. A 6kb fragment of the P{PZ} element remains, containing the Ecol\lacZ gene and part of the ry gene.

Detailed Description
Statement
Reference

Homozygous larvae show transformation of PS12 into PS13 on both the ventral and dorsal sides of the ectoderm. Homozygous adult females also show transformation of PS12 into PS13 in the cuticle. The 7th tergite is nearly absent and resembles the 8th tergite in both size and colour (it is unpigmented). The 7th sternite is absent. Thorn bristles, normally found on the vaginal plate, are occasionally seen in the place of 7th sternite bristles.
