  • a All were at 22°: h1 ca1 males × h1 ca1 virgins with the following X chromosome genotypes: (1) scM6w/+; (2) scsisB1 w/+; (3) y scsisB2/+; or(4) y scsisB3/+.

  • b Only the dorsal side was scored; no scutellar microchaetae were found on a sample of 25 sc+ h+ males.

  • c Pooled results for groups of 30 males each from crosses 1, 3, and 4, and 60 from cross 2, with means of 31.6, 27.5, 27.4, and 28.1, respectively.
