  • * Number indicates testes with at least one clone 2 or 7 days after clone induction.

  • The lethalstat92E06346 allele is associated with a P-element insertion carrying the lacZ gene (24).

  • The lethalstat92E105 allele has an ethylmethane sulfonate–induced mutation (25).

  • § ND, not determined.
