  • a All crosses were at 22°. For X-linked sc alleles, y w sisA1/Ymales × virgins as follows: (1) scsisB1w/Binsinscy; (2) y scsisB2/Binsinscy; (3) y scssiB3/Binsinscy; (4) scM6 w/Binsinscy; (5) scM6/Binsinscy; (6) yscT1 w/Binsinscy; (9) scM6/y scsisB2; and (10) scM6/y scsisB3. For the two sc alleles carried on Dp(1;2)sc19 (crosses 7 and 8): Df(1)sc19,y pn w/Binsinscy × yw sisA1/Y; Dp(1;2)sc19,y+ scmutant/+.

  • b The genotype of experimental females in crosses 7 and 8 is Df(ASC)/sisA1; Dp(ASC),scmutant/+, which is equivalent to scmutant sisA+/sc+ sisA1.
