Southern analysis indicates a lesion within a 4kb HindIII fragment at the 5' end of the w gene in the P{wAR}fru0-1 element. RT-PCR analysis suggests that there is a breakpoint between the P2 and P3 promoters of fru.

1-2% fruw12/fruw27 adult escapers are seen. 5% frusat15/fruw27 adult escapers are seen. 0.1% fruw9/fruw27 adult escapers are seen. 3% of fruw27/fruM5 males are fertile. Male-female courtship as measured by courtship index (CI) or wing extension index (WEI) is almost completely abolished in fruw12/fruw27 or fru4-40/fruw27 males. Male-female courtship as measured by courtship index (CI) or wing extension index (WEI) is almost completely abolished in fru3/fruw27 or fru4/fruw27 males. Male-female courtship as measured by wing extension index (WEI) is almost completely abolished in fru0-1/fruw27 males. fru1/fruw27 males show significantly more male-male courtship and less frequent male-female courtship than wild-type males. fruw27/fru1 or fruw27/fru4 males show substantial chaining. fruw27/fruM5 or fruw27/fru4-40 males show substantial chaining. Heterozygous males generate a normal courtship song except that the width of the fast-Fournier transform is smaller than in wild-type males. fru3/fruw27 and fru4-40/fruw27 males do not produce a courtship song even though they show a small amount of wing extension. fru1/fruw27 males have a courtship song with longer interpulse intervals, but essentially normal intrapulse frequencies, cycles per pulse and width of the fast-Fourier transform compared to control males. fruw12/fruw27 animals are able to emerge if dissected from the pupal case. These animals perform posteclosion behaviours such as wing and proboscis expansion but are unable to fully extend their wings, which project from the body at a 70-90o angle. The tibial segment may be bent. Leg joint defects and duplicated bristles are seen. fruw27/Df(3R)fruw24 adults that have been dissected from the pupal case show minor external defects, such as uninflated wings, wings held at a 70-90o angle to the body, leg joint defects and duplicated bristles. Abdominal motorneurons of fruw12/fruw27 animals produce fewer lateral terminal arborisations as they terminate on lateral muscles compared to wild type. Abdominal motorneurons of fruw27/Df(3R)fruw24 animals produce fewer terminal branches compared to wild type. Abdominal muscle innervation appears normal in fruw27/fruM5 adults. The number and pattern of divisions of larval neuroblasts in the thoracic ganglia or brain appears normal in fruw27/Df(3R)fruw24 animals.
Transheterozygotes with fruw12 or Df(3R)fruw24 are lethal, 2% fruw12/fruw27 transheterozygotes survive to adulthood. fruw27/Df(3R)ChaM5 males barely court at all but show normal locomotor activity. Mutant combination shows some male-male chaining. Early and late steps of courtship are disrupted.
