93% of fru0-1/fruM5 males are fertile. 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 fruw9/fruM5 males. Male-female courtship as measured by courtship index (CI) or wing extension index (WEI) is completely abolished in frusat15/fruM5 males. fruw9/fruM5, frusat15/fruM5 or fruw27/fruM5 males show substantial chaining. fruw12/fruM5 males do not produce a courtship song even though they show a small amount of wing extension. Abdominal muscle innervation appears normal in fruw27/fruM5 adults.
