Detailed Description
Statement
Reference

0.1% fruw9/fruw27 adult escapers are seen. 7% of fru0-1/fruw9 males are fertile. Male-female courtship as measured by courtship index (CI) or wing extension index (WEI) is almost completely abolished in fruw9/fruM5 males. Male-female courtship as measured by courtship index (CI) or wing extension index (WEI) is almost completely abolished in fruw9/fru4-40 males. Male-female courtship as measured by courtship index (CI) or wing extension index (WEI) as measured by WEI is almost completely abolished in fru3/fruw9 or fru4/fruw9 males. Male-female courtship as measured by wing extension index (WEI) is almost completely abolished in fru0-1/fruw9 males. fru1/fruw9 males show significantly more male-male courtship and less frequent male-female courtship than wild-type males. fruw9/fru1, fruw9/fru0-1, fruw9/fru3 or fruw9/fru4 males show substantial chaining. fruw9/fru4-40 or fruw9/fruM5 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. fru1/fruw9 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.
