  • a w++ means flies carrying two w+ markers; distinguished by their darker eye color. A few flies ambiguous for the Cy phenotype were excluded.

  • b Calculated as (number of flies in the seventh or eighth class) divided by (number of flies in the sixth class).

  • c Crossed with w; Int(2L)D+S, Nup160sim/SM1; Nup96sim/+ males. The balancers SM1 and TM3 have Cy and Sb (and Ser) as dominant markers, respectively.

  • d One was ebony presumably caused by a rare male recombination or a spontaneous mutation.

  • e One was a gynandromorph.
