WT hermaphrodite if grown at 15-20C. WT females if grown at 25C. When crossed, these females yield only XX viable hermaphrodite progeny, all XO progeny are dead.

Vab XX hermaphrodites and XO males, viable at all temperatures. Adult hermaphrodite tail spike is invariably shortened and/or vacuolated, often also abnormal in larvae. Possible excretory cell abnormalities. Rays of adult male tail variably abnormal, other structures normal; males can mate.
