Imprecise excision of the progenitor insertion, resulting in deletion of the 3' UTR.
Inferred boundaries of a deletion resulting from the imprecise excision of Mi{ET1}CowMB00767 that starts 396 bp downstream of the Cow ORF and extends 9,119 bp downstream.
Homozygous mutants are mostly embryonic lethal; 50% die before cuticle formation, and 9.5% of embryos show a weak denticle belt fusion phenotype.
When Cow5Δ clones are generated in the wing disc, 89.4% of mutants die before the larval stage, and 9.3% die at the pupal stage. The escapers (1.3%) all show a wing-loss phenotype.
Cow5Δ has ventral denticle belt phenotype, enhanceable by wg[+]/wgl-17
Cow5Δ has ventral denticle belt phenotype, non-enhanceable by smo[+]/smounspecified
Cow5Δ has ventral denticle belt phenotype, non-suppressible by smo[+]/smounspecified
