Imprecise excision of the P{PdL}fipi3404z progenitor, resulting in a 719bp deletion ( 2L:4793237..4793955 , FB2016_01) that removes part of the first fipi exon downstream from the site of P{PdL}CG156303404z together with a part of the first intron.
A 719 bp deletion resulting from the imprecise excision of P{PdL}fipi3404z removes most of the first exon of fipi and part of the first intron. It was mapped to 2L:4793237..4793955 .
fipi362 males show significant decrease in the duration of interpulse interval during their courtship song, whereas the pulse train duration as well as the number of pulse trains per 100s are comparable to controls.
