amorphic allele - molecular evidence
Although Asx22P4 homozygous embryos fail to express detectable amounts of Asx protein, a lesion in the Asx open reading frame has not been found.

Segments A5-A7 of the cuticle are partially transformed into copies of A8 in stage 16 homozygous embryos.
Asx22P4 has embryonic/first instar larval cuticle phenotype, enhanceable by SceKO
Asx22P4 has embryonic abdominal segment 8 | ectopic phenotype, enhanceable by SceKO
SceKO enhances the segmentation defects seen in Asx22P4 embryos: segments T2-A7 in the cuticle are extensively, but not completely, transformed into copies of A8 in stage 16 double homozygous embryos.
