Imprecise excision of the P{GawB} element. Scer\GAL4 sequences are still present. w sequences are still present but the size of the w fragment is altered compared to prosV1. A 2.9kb BamHI-PstI fragment ("pBSK") from the 3' end of the element appears to be intact. Surrounding genomic sequences are unaffected.
The median lifespan for prosV8 animals (the age after egg laying at which 50% of homozygotes have died) is 3.16 days at 25oC.
Homozygous third instar larvae show reduced locomotor activity compared to controls.
Homozygous second instar larvae are indifferent to 0.1M sucrose and to 0.3M NaCl in a taste response assay, in contrast to wild-type larvae which are significantly attracted by sucrose and significantly repulsed by NaCl.
The courtship index of heterozygous males towards decapitated Canton-S males is not significantly different from that of wild-type males towards decapitated Canton-S males.
